The half-life of Kr 76 was determined by parent-daughter separation and by growth and decay of Br 76. The value of t 1 2 = 14.8±0.1 h was obtained. Observation of the γ spectrum indicated peaks at ≈ 0.040, 0.073, 0.104, 0.135, 0.197, 0.267, 0.316, 0.360, 0.407 and 0.452 MeV....
"It [a half-life of 30 years] means that it takes 30 years for 1 kg of 1 Cs to be reduced to 1/2 kg. The mass decreases because the substance gives away alpha irradiation, which is particles." The answer betrays a lack of understanding that disintegration(解体) of a radioactive ato...

I grieve for people who needlessly suffer these illnesses and hold out the hope that our government leaders will become more cognizant of the role electromagnetic factors are playing in disease, health care costs and the erosion of quality of life and productivity in America."...
Many of the key properties of photons as elementary particles relate to the fact that they have an intrinsic spinS= 1, and so are classified asbosons(particles with integer spin as opposed to half-integerspin particlesof matter such as electrons). As such, photons collectively display a behavio...
Cesium-137 has a half-life of approximately 30 years. As of 2005, caesium-137 is the main source of radiation in the Exclusion Zone around the nuclear power plant. Together with caesium-134, iodine-131, and strontium-90, caesium-137 was among the isotopes distributed by the reactor explosio...
