Question text Nuclear radiation is damaging to living matter by ionizing atoms and breaking molecular bonds. Which type of radiation produces the largest number of ionization events? (Consider that the initial energy of the alpha, beta, and gamma particle is the same.)
Homework Answers
Alpha and Beta radiation are not very harmful to living beings if used in a limit . In fact, beta rays are being used in cancer treatments.
Gamma rays are often considered the most dangerous type of radiation to living matter. These are basically forms of energy. They have large penetrating range and can diffuse through many cells before dissipating. They have extremely high penetrating power .

write a summary : 5.4.4 Radiological Hazards Radiological hazards can be divided into three general forms: alpha, beta, and gamma radiation, which are emitted by radio- isotopes that may occur as an aerosol, be carried on particulate matter, or occur in a gaseous state. Alpha particles, consisting of two neutrons and two protons, are the least penetrating and the most ionizing form of radiation. They are emitted from the nu- cleus of radioactive atoms and transfer their energy at very...
