A 60-kg person accidentally ingests a small source of alpha particles (RBE=15). The activity of the source is 0.04 Ci, the half-life of the source is 110 years, and each alpha particle emitted has an energy of 0.586 MeV. It takes 12hours for the alpha source to pass through the person’s digestive system and exit the body.  How many alpha particles are absorbed by the person (assume that 100 percent of the alpha particles emitted by the source are absorbed by the person)? How much energy, in Joules, is deposited in the person by the source? What is the absorbed dose in rad? What is the absorbed dose in rem?

A banana contains the naturally occurring radioactive isotope potassium K-40 which undergoes Beta minus decay. Write the Beta decay formula to include the daughter isotope and the ejected particles.

Give good explanation Asap Thanks

What isotope is produced when Np-239 emits a beta particle?

Elements that appear in the same column of the periodic table often share similar chemical properties. In the case of the alkaline earth metals, this is troublesome since the body treats calcium (necessary for proper bone growth) and radium (a radioactive element) as chemically similar, storing both in bone marrow. The radium then bombards nearby bone cells with alpha particles, causing them to "crumble." Radium poisoning investigations often center on the identification of radium and its isotopes in bone samples using lonized isotope a mass spectrometer. Pictured is a schematic of a simplified mass spectrometer that shows the paths of calcium isotopes, barium (another alkaline earth metal) isotopes, and radium isotopes entering the chamber. The region shown is immersed in a constant magnetic field of 0.552 T pointing out of the plane of the schematic. Motion of the positively-charged isotopes toward the right was initiated by a potential A -AV- B difference of 3082 V on the two plates…
