The radiation fear campaign has been going on in earnest since June 13, 1969. That was the date when the New York Times ran a front page headline stating that “SCIENTISTS TERM RADIATION A PERIL TO THE FUTURE OF MAN.”
Have you ever seen someone eat a banana? Bananas are radioactive, but the dose is small.

Radiation is no big deal. This guy eats some in this video.
The actual men in the room at the time: Louis Slotin (died nine days later), Alvin Graves (died 19 years later of a suspected radiation-caused heart attack, had cataracts and severe thyroid problems - he was three feet away), Stanley Kline (died of natural causes 55 years later - eight feet away), Dwight Young - (died 29 years later from a blood disorder that stunts development of white and red blood cells and an infection of the lining of the heart - six feet away), Guard Pat Cleary (KIA in Korea), Raemer Schreiber (died of natural causes at age 88 - 16 feet away), Theodore Perlman (Alive and in good health as of 1978 - 16 feet away), Marion Cieslicki (died of Leukemia, and his liver and spleen were abnormally large at autopsy - he was eight feet away). The bottom line, Louis Slotin (portrayed in this scene) really endangered his co-workers. The biggest mistake? Removing the shims (supports) and using a screwdriver instead - which slipped.
the US dropped more than 270 million bombs in Laos as part of a CIA-run, top-secret operation aimed at destroying the North Vietnamese supply routes along the Ho Chi Minh trail and wiping out its local communist allies. One-third of the bombs failed to explode on impact

Thx 4 replies, my Friends.
here we go then. let's see some statistics...

so, even chemical explosives haven't had fail-proof fuses. Nuclear charge provides significantly another story == there needs geometrically ideal shock wave to ignite chain reaction + radioactive decay spoils geometry of fissile material, its chemical purity & radiation makes toll upon chemical detonators too. In short, the're no way to keep all-ready arsenals for long time.
Correct. Nuclear reactor fuel still needs cooling for some time after the reactor is turned off. The Fukushima accident shows what can happen if that cooling isn't provided.

No it doesn't. Fissile material that's reacting requires cooling, such as in a nuclear reactor.
Maybe it produces a little bit of heat, but not enough to require any cooling. If it didn't produce a little heat, the earth might be an ice ball. We get half our Earth heat from naturally decaying Uranium and other elements.
A nuclear weapon core isn't generating heat, until detonation.
29 sounds closer to 2/3 of 44 than 1/2 of 44 to me, but whatever the exact amount, radioactive decay produces some heat, even from unrefined natural Uranium in the Earth.
research has shown that Earth's total heat output is about 44 terawatts, or 44 trillion watts. The KamLAND researchers found roughly half of that -- 29 terawatts -- comes from radioactive decay of uranium, thorium and other materials
The maximum temperature of the spent fuel bundles decreases significantly between two and four years, and less from four to six years. The fuel pool water is continuously cooled to remove the heat produced by the spent fuel assemblies. Pumps circulate water from the spent fuel pool to heat exchangers, then back to the spent fuel pool. The water temperature in normal operating conditions is held below 50 °C (120 °F).[7] Radiolysis, the dissociation of molecules by radiation, is of particular concern in wet storage, as water may be split by residual radiation and hydrogen gas may accumulate increasing the risk of explosions. For this reason the air in the room of the pools, as well as the water, must be continually monitored and treated.
