Okay .. I'm not trying to be an alarmist and this is just my personal opinion but .. posting this as fyi in case things completely go south with Japanese nuclear reactors. Hopefully officials can contain all since structures have multiple safeguards, but sharing this in the event a complete failure or meltdown could potentially impact the west coast of North America. (Please note, I'm not talking about anything released to date .. there are no concerns with that whatsoever. Just thinking worse case scenario.)
Hopefully you have KI and radiation detection units on-hand because if reactors blow and release massive amounts .. well, again - let’s just hope it all stays contained.
Just remember .. TIME, DISTANCE and SHIELDING are important during any type of radiological disaster. And radioactive materials decay rapidly .. per 7/10 rule, for every sevenfold increase in time, there is a tenfold decrease in radiation rate. For example, 75 Rems (rad) would drop to 7.5 Rems after 7 hours. Best thing you can do IF this even happens is .. stay inside a structure (don’t be running around outdoors) and stay put for hours or a day or 2 until it decays. Also move livestock and their food and water supplies into structures to protect them from fallout (esp milk producing critters.)
USFRA has nuclear power plant accident tips posted here
.. and learn how to build an expedient shelter here
. (I can also provide these in PDF if any of you want them for local communities.)
Also, if you don’t have access to KI, get a bottle of iodine from a local pharmacy so it’s on your shelf .. then and only IF
instructed .. wipe a swipe on your abdomen. It’ll stain your skin but it can fill up your thyroid with good iodine so it doesn’t absorb bad stuff. Children (including unborn) are most susceptible since their thyroids are still active.
But also remember as a plume gets carried by winds, it will dissipate so there's no way to know how much intensity (IF ANY) would remain in fallout.
don’t panic and try not to obsess over the news .. but do stay current on events and try to educate yourself and others as best as possible. The International Atomic Energy Agency site is http://iaea.org
and US Nuclear Regulatory Commission site is http://www.nrc.gov
.. and obviously officials and media will be monitoring all this too. stay safe out there, j
