Nuclear Disaster Preparedness Japan is a country known for its state-of-the art technology and particularly for its preparedness for earthquake damage. Who could have imagined that the quake of March 11, 2011, would be so intense... the tsunami so devastating... the nuclear power plants’ safety systems rendered so frighteningly useless? The takeaway here is that the worst-case scenario can surprise any of us -- and preparedness is essential. A 2010 survey of state health departments, published in the March 14, 2011 issue of Disaster Medicine and Public Health Preparedness, warned that most US states are not prepared to deal with a nuclear emergency. That may start to change for the better now, but no matter where you live, you can and should take your own steps to protect yourself and your family. Here’s what you need to know to survive a release of radiation from a nuclear power plant, whether due to an earthquake, a malfunction in an aging plant -- or even a terrorist attack... PLANNING FOR THE SITUATION YOU’RE IN A look at the current crisis in Japan shows people coping with a wide range of situations. Some were located in "the evacuation zone" within 12 miles of the reactor, where everyone was asked to leave (the US has set the limit for Americans in Japan higher and calls for a 50-mile evacuation). Others are located in a "take shelter zone," 12 to 19 miles from the reactor. Beyond that, by Japanese standards, you are in the safe zone. The US asks for a measure of "beyond 50 miles" to meet this qualification. So planning for a family’s safety in one situation as opposed to another could be quite radically different. Whether you will stay or not, and for how long, will depend on what officials tell you to do based on the particulars of the situation, but a key lesson is to be prepared to hunker down for quite a few days in case you can’t leave immediately. In Japan, if you were fortunate enough to be in the safe zone, the questions you faced were very straightforward. You watched the news, assessed the most reliable information you could, and either made plans to stay or gathered your family and went as quickly as possible to friends or relatives who you felt could offer you safer haven. If however, you were living within either of the areas closer to the radiation leak -- either "the evacuation zone" or the "take shelter zone" -- you would have needed a very different kind of plan. Some family members might have been at their places of business at the onset of the emergency... others at school or elsewhere. Deciding in advance where, when and how you would all make contact could have been critical. And you would need to have a plan B as well, as there is no way to know in advance which parts of a community, town or region would be safest -- or where it would be safest to meet. The lesson: Make sure you all carry your cell phones and have each other’s numbers and that everyone knows how to send and receive text messages. If the cell-phone network goes down, text messages sometimes get through when voice phone calls cannot. Taking Shelter Once your family members are accounted for, people in the evacuation zone would do just that -- evacuate. For that group and for the "take shelter" group, radiation would become the next, primary concern. You would need to protect yourself and your loved ones against the escape of radioisotopes such as Iodine 131 and Cesium 137, which can respectively cause thyroid cancer or general cell damage that could result in cancer years down the road. If you absolutely must go out of doors, protect yourself as best you can by covering all skin, including wearing a hat and gloves even if the weather is warm. James H. Thrall, MD, radiologist-in-chief at Massachusetts General Hospital and professor of radiology at Harvard Medical School, told me that there are medicines to help (more on this below) and practical steps that can be taken to keep yourself as safe as possible from the dangers. Remove Contaminated Clothing If you’ve been outside and may have been contaminated, get into an area that is free of contamination and quickly remove your clothing and shoes. This eliminates about 90% of external contamination, according to the Mayo Clinic. Place all clothing in a plastic bag, seal or tie it and place it as far away as possible from humans and animals. (Later you can call local authorities and ask about the proper disposal of this hazardous waste.) Take a Shower To remove any remaining radioactive particles, take a shower using plenty of soap and hot water if it’s available. Gentle washing -- not scrubbing -- is best, since you don’t want to break your skin and allow particles to enter. Use shampoo but not conditioner in your hair. Conditioner binds with radioactive material and keeps it from rinsing out easily. Gently blow your nose, and wipe your eyelids, eyelashes and ears with a clean, wet cloth. Wash feet extra well, especially if they have gotten wet in water that could have contained contamination. (Afterward, dispose of any cleaning materials along with your clothing.) Seal Out Contaminants Put duct tape and plastic sheeting around windows and doors to seal out contaminants. Close vents, fireplace flues and other openings. Use an air cleaner with a HEPA filter to remove airborne contaminants -- it might be a good idea to buy one now if you don’t already have one. Emergency Supplies Emergency supplies will be critical while you wait or once you are on the move. (Be sure to assemble these things and keep them in your house, just in case we have a nuclear emergency in the US.) - Water. One gallon per person per day for at least three days, for drinking and for sanitation.
- Food. A three-day supply of cans (and a few can openers) plus other nonperishable items that require little or no preparation, no cooking and very little water to prepare -- such as jars of peanut butter, dried fruits, crackers and nuts. Also include a supply of infant formula, if appropriate.
- Face masks for filtering particles from contaminated air. Ordinary face masks used in medical applications are not effective as they do not fit tightly enough, Dr. Thrall said. But there is another class of face mask typically referred to as a "respirator" that can be form fitted. These are very effective in filtering even virus-sized particles. For more information about respirators, including the N95 filtering face piece respirator certified by the CDC/National Institute for Occupational Safety and Health (NIOSH), check their Web site at www.cdc.gov/niosh/npptl/topics/respirators/factsheets/respfact.html.
- A battery-powered radio and a National Oceanic and Atmospheric Administration (NOAA) Weather Radio with tone alert will provide immediate access to official information in case of emergency. Be sure you have plenty of extra batteries. In addition you should have a hand-crank radio -- shop now for one that incorporates a built-in cell-phone charging receptacle.
- Flashlights. Batteries run out much quicker than most of us anticipate. Consider also a Forever Flashlight (or similar brand), which does not need batteries. Instead, shaking it for 30 seconds charges a capacitor to provide five to seven minutes of light. A flashlight with an LED bulb will run longer than a standard one.
- Plastic sheeting, scissors and duct tape for sealing off a safe area in your house.
- A first-aid kit with sterile gloves and dressings, adhesive bandages and eyewash to use as a decontaminant is critical as well. Also keep on hand a supply of your prescription medications. (Rotate these periodically due to expiration dates.)
- A good, strong whistle on a long string for each person in your family to signal for help if necessary.
Other items: Cash, extra eyeglasses, pet food and extra water for your pet, sleeping bags or warm insulated blankets, changes of clothing, diapers and copies of important family documents such as passports, birth certificates and insurance policy papers. WATCH WHAT YOU EAT AND DRINK Do not consume local produce until government monitors confirm that radioactive isotopes have decayed to safe levels. Food Safety officials in Japan found that Iodine 131 in their tested milk was up to five times what the government deems safe, and spinach had levels of more than seven times the safe level. Shipments of both milk and spinach were halted. But certain types of radioactivity decay rapidly. For example, Iodine 131 has an eight-day half life, so it is nearly all gone in two and one half months, says Dr. Thrall. COPING WITH THE FALLOUT In the years following the 1986 Chernobyl nuclear power plant disaster, during which large concentrations of Cesium 137, Iodine 131 and other radioactive isotopes were released, an epidemic of thyroid cancer developed because children drank milk from cows grazing on grass contaminated by fallout. Children and fetuses are particularly vulnerable to the effects of radiation because they are still growing and their cells are rapidly dividing. That is why exposed children and pregnant women should be the first to be given the most protective medicine available -- potassium iodide pills. But since the exposure to radioactive elements such as iodine and cesium may be gradual you may be able to protect yourself... When to Take Potassium Iodide Following the nuclear incident in Japan, there was a worldwide run on potassium iodide (KI), which protects people from radiation-induced thyroid cancer. These over-the-counter tablets work by flooding the thyroid gland with nonradioactive iodine so that radioactive iodine cannot be absorbed. But KI can harm you if it’s taken unnecessarily. So the question is, how do you know whether you’ve been exposed to radioactive iodine? According to Dr. Thrall, "In some cases, you cannot tell if you’ve been exposed, but anyone known to be within an established zone of higher fallout is presumed to have been. The real question is the uncertainty of how much the exposure has been and whether taking potassium iodide is necessary. People should understand that a small fraction of people will have an allergic or other reaction to potassium iodide, and a small fraction may develop either hyperthyroidism or hypothyroidism depending on the status of their thyroid glands, something that is also typically not known. That is why it is not recommended that people take potassium iodide without a substantial reason. They should wait for an official announcement about it." If you do end up taking KI pills, Dr. Thrall said it’s best to do so within two to four hours of exposure. Typical doses: Age 18+, 130 mg daily... age three to 18, 65 mg daily... one month to three years, 32 mg daily... birth to one month, 16 mg daily -- until authorities announce that there is no more risk for exposure. In 2002, the US Congress passed legislation requiring the government to supply potassium iodide to everyone living within a 20-mile radius of a nuclear power plant -- but no administration has ever implemented the provision, and I’d hate to wait for an emergency to test the distribution system. You can buy the pills yourself online and at many pharmacies -- just be sure they are made by one of the FDA-approved companies -- such as losat tablets ( www.anbex.com), ThryoSafe tablets ( www.ThyroSafe.com), or ThyroShield solution ( www.ThyroShield.com). Remember that KI protects against only thyroid cancer. There are other cancer risks associated with radiation exposure, and medications to help reduce your risk might include medications to stimulate your bone marrow to manufacture more cells or drugs to rid the body of radioisotopes. For example, Prussian blue is a dye that binds to the radioactive particles cesium and thallium and can be used as an antidote after exposure. So those who are exposed to a radiation leak should stay in close touch with their physicians and consider more frequent screenings to counter any exposure-related cancer risk. In Dr. Thrall’s opinion, the biggest ongoing health problems after most nuclear power plant incidents are psychological -- having been close to radiation causes mental anguish and it is impossible to know how one’s future might have been altered by the event. This stress can be debilitating for some people if not addressed -- so be sure to reach out and get the emotional as well as physical health support you need following any disaster. Source(s):

The 10 Biggest and Deadliest Heart Myths The number of heart attacks has increased by 27 percent over the past 20 years, in spite of all the supposed advances of modern medicine. What's going on here? Could we be mistaken about some things? Perhaps we're under some major misconceptions about heart disease. Like... Myth #1 -- Heart disease and heart attacks are an inevitable part of aging. Myth #2 -- Cholesterol is the main cause of heart disease and heart attacks. Myth #3 -- Blood pressure drugs help you avoid heart problems and live longer. Myth #4 -- Aggressive, "type A" behavior increases your risk of a heart attack. Myth #5 -- Low-fat, low cholesterol diets are good for you and your heart. Learn more...
Can Daydreaming Be Bad for Your Health? Intriguing new research from Harvard has used trendy technology to learn that daydreaming makes people unhappy. "A human mind is a wandering mind, and a wandering mind is an unhappy mind," says Matthew A. Killingsworth, a doctoral student in psychology at Harvard -- who was happy to focus on sharing the results of his research when I called him recently. Dreaming Your Life Away In 2009, Killingsworth and his colleagues launched an iPhone Web application, "Track Your Happiness" ( http://www.TrackYourHappiness.org/), to study the causes of happiness in everyday life. At random intervals, they contacted 2,250 volunteers (average age 34) to see what they were doing at that moment... what they were thinking about (specifically, whether they were thinking about their current activity or something else)... and how happy they were (on a scale of 0 to 100). Killingsworth and his team were surprised to discover that people spent nearly half their time (47%) daydreaming or thinking about things other than what they were doing. In an analysis of 250,000 responses, they also found that... - People’s minds were least likely to wander during sex. When asked what they had been thinking about, 90% of those making love said they had been completely engaged in that activity.
- During every activity other than sex, people’s minds wandered at least 30% of the time. Not surprisingly, mind wandering was most common during personal grooming tasks such as brushing teeth, showering and dressing (as high as 65%) and commuting and traveling (over 60%).
- People were happiest during sex. Participants gave sex a 90% rating on the 0-to-100 feelings scale, followed (in descending order of happiness) by exercising (about 15 points lower), conversing, listening to music, taking a walk, eating, praying and meditating. Personal grooming, commuting and working ranked lowest for happiness.
Be Here Now -- Or Else The rate of mind wandering was clearly lower during more enjoyable activities, but whatever people did -- whether it was having sex or commuting -- they were happier when focused on the matter at hand rather than thinking about something else. The psychologists found that if someone’s mind wandered away from the task at hand, a short time later (say, 15 minutes) he/she was apt to report being less happy. Crunching the numbers further, the investigators estimated that mind-wandering status was responsible for nearly 11% of a person’s state of happiness, and the nature of the current activity for only 4.6%. These findings were published in the November 12, 2010, issue of the journal Science. Fix Your Focus Mind wandering is an excellent predictor of people’s happiness, says Killingsworth -- in the vast majority of cases (outside of sex), it was a better indicator than the activity they were engaged in. Given this conclusion, I asked him what advice he had for my readers. Is this, in simplest terms, a wake-up call that if you want to be as happy as you can be, you really should try to "live in the moment?" The study results suggest that this is the case, Killingsworth replied, but more research is needed to know for sure and to know how best to do so. In the meantime, the study is continuing. More than 5,000 people are now using the researchers’ iPhone Web app, and anyone with an iPhone can participate. Source(s):

Do You Coupon? I love clipping coupons. I find it very relaxing to shop -- with my sole focus on shopping the coupons and saving money on other in-store bargains. My "game" is to save at least $20/trip at the supermarket, and at least 30% when I buy higher-priced items at other stores. Read on...
Be well,
