Question

What is the ionization power of alpha rays?
A. Low
B. Very low
C. High
D. Very high ​

Answer 1

Answer:

Alpha particles are highly ionising because of their double positive charge, large mass (compared to a beta particle) and because they are relatively slow. They can cause multiple ionisations within a very small distance. ... Alpha-particle emitters are particularly dangerous if inhaled, ingested, or if they enter a wound..
