How much distance should i put myself from a nuclear disaster area?

Go far, and upwind: Get as far away as you can, from any radiation leak or radioactive explosion. The more distance between you and fallout particles, the better for your long-term health.

Why do you ask?: It depends on the amount of radioactivity. If it's an atomic bomb, it's moot -- if you can flee, do so. If it's some crackpot exploding a device that contaminates a major city with nuclear waste -- well, it finally happened, but the excitement will be greater than the actual danger. May I ask why you're asking all these questions about disasters, friend? Best wishes.

Nuclear disaster: It depends on the magnitude of nuclear spill, wind direction and other factors. Geiger count is helpful

As much as possible: In case of nuclear disaster, the best thing to do is evacuate as far upwind from the area as possible. Listen to the local news outlets since most of us rely on them to monitor radiation levels. The US govt recommended that Americans living in Japan evacuate at least 50 miles from the Fukushima Nuclear plant after their disaster in 2011 if that's any help!

Depends: It all depends on how the radioactive material spreads and how much radioactivity is emitted. The disaster team will usually issue such a guideline in these events. Be sure to have a battery operated radio handy to get the message.

Nuclear disaster: The short answer is as much distance as possible. The more exact answer would be at least 50 miles and if the wind is blowing the radioactive cloud in your direction that still may not be far enough.

Far: A nuclear disaster area has hazards of heat, radiation, contamination, and fire. Immediately upon notification head for a shelter or, if possible, head away from the area in the opposite direction of the winds. Concrete, dirt, lead, and cement as well as water, are excellent materials to use as shelter, but as far away from the main area as possible. At safe distance, begin decontamination.

Well: Let's hope this does not happen or there is no place that is safe. Remember Chernobyl? Still effects of this disaster. Let us just pray this never happens again
