An airburst N-bomb would have little fallout nor would it destroy structures, equipment or vehicles, but its neutrons would kill the humans either outside or within buildings or tanks.
Russian military pilots have described how they created rain clouds to protect Moscow from radioactive fallout after the Chernobyl nuclear disaster in 1986.
Oddly, the Tokyo fallout data is a bit higher than other prefectures around it and begs the question if the higher amounts are from the incineration of radioactive debris at Tokyo's 23 ward incinerators(55)?
Even though the area contaminated by radioactive fallout from the Fukushima plant is smaller than the region contaminated by the Chernobyl disaster(1986), radiation levels in some places are similar.
Belarus, which received 80 percent of the fallout from Chernobyl, still has one fifth of its agricultural land that is unusable, which is costing the Belarus economy $700 million a year.
As radiation hot spots emerge in Tokyo and nuclear contamination plagues the country, some Japanese are fleeing to the Okinawa island chain to avoid the fallout from Fukushima.
Divided over the entire month that comes to less than one becqueral per day, if you were breathing in all the air in that spot you would breathe in some of the radioactive fallout.
Apart from the damage caused by blast, fire and radioactive fallout from actual use in warfare, the weapons impose major financial, moral and political costs on nuclear weapons states and countries that host the weapons.
The death toll from the atomic bombing totalled 73,884, as well as another 74,909 injured, and another several hundred thousand diseased and dying due to fallout and other illness caused by radiation.
Most such models either rely on the fact that hydrogen bombs can be made arbitrarily large(see Teller-Ulam design) or that they can be“salted” with materials designed to create long-lasting and hazardous fallout(e.g.; a cobalt bomb).
They have worked together since 2000 studying the impacts of radioactive fallout around Chernobyl, and since July 2011 they have conducted field studies to determine whether fallout from Fukushima is likely to have comparable impacts to those documented in Chernobyl.
Our finding that the actual vs. expected ratio in California airborne beta in the month after Fukushima fallout arrived were over four times greater than in non-western sites(10.53 vs. 2.55 times above the expected) supports the understanding that the western and Pacific US received the greatest exposures, raising risk of subsequent adverse health effects.
At issue is not only the risk of radioactive fallout that could affect Russia's Far East- just the mere threat of contamination last year plunged the residents of Russia's Far Eastern regions into a panic, with many rushing to local pharmacies to stock on iodine- but more radioactively contaminated export goods finding their way across the border.
