Alpha Factor
Help the year of 11 questions in physics?
1. Why is alpha radiation as a factor of better quality than the gamma radiation? 2. How much energy is absorbed by gamma rays, which cause the death of a person of 80 kg in 48 hours due to damage of the vascular system? 3. Australians receive on average of 2.0 mSv of radiation each year. Assuming that this radiation is all beta particles with an energy of 1.0 MeV particles Beta passing into or out of your body every second? (Hint: Calculate your body mass and how many joules of radiation you receive each year. Find out how many joules of energy in the 1.0 MeV beta particles, and then see how many beta particles passing through his body each year every second.)
