Problem: Although alpha radiation is the most ionizing radiation because the nuclear charge is +2, it is the least damaging because: A. Alpha radiation is the least damaging to living things because it has relatively low energy and is absorbed by matter including smoke, thin sheets of paper and dead skin.B. Alpha radiation is the least damaging to living things because it is not absorbed by anything, it just passes through all matter.C. Alpha radiation is the least damaging to living things because it is made of helium and helium is an inert gas.D. Alpha radiation is the least damaging to living things because it carries a positive charge, and that charge cannotcause ionization.

We are asked why alpha radiation is the least damaging type of radiation. 


For alpha decay, an alpha particle (42α, atomic mass = 4, atomic number = 2) is formed as a product.

  • Alpha particles are the least dangerous in terms of external exposure

Although alpha radiation is the most ionizing radiation because the nuclear charge is +2, it is the least damaging because:

A. Alpha radiation is the least damaging to living things because it has relatively low energy and is absorbed by matter including smoke, thin sheets of paper and dead skin.

B. Alpha radiation is the least damaging to living things because it is not absorbed by anything, it just passes through 

all matter.

C. Alpha radiation is the least damaging to living things because it is made of helium and helium is an inert gas.

D. Alpha radiation is the least damaging to living things because it carries a positive charge, and that charge cannot

cause ionization.
