What To Do If A Radioactive Cloud Is Coming
Close all doors and windows and fireplace dampers (exposed to outside air) Turn off all fans, air conditioners and heating units that bring in air from the outside (since it may be contaminated) Bring the family and pets inside. Move to an inner room or basement because it affords much higher radiation shielding
If significant amounts of radioactivity from the Fukushima plume approach populated centers in any country (e.g. the western USA) the European Committee on Radiation Risk advises:
• Do not believe assurances from radiation protection advisors working for any government. They are based on an obsolete model. This is a potential Chernobyl level event and must be seen as extremely serious.
• If possible obtain a Geiger Counter or a similar radiation detector or readings from someone who owns one. If the readings increase to more than twice the normal background in your area or to a level of more than 300nSv/h (300nGy/h) then:
• Get away as soon as possible to a clean area. If it is not possible to evacuate, stay indoors and keep all the doors and windows closed for as long as the radiation levels are higher than normal. Try to keep the house sealed as far as possible.
Drink bottled water, use only tinned milk. Avoid fresh garden produce. (We acknowledge that this is difficult advice for the people of Japan,
