about radiation
There are four primary types of ionizing radiation – alpha, beta and gamma radiation as well as x-radiation (x-rays).
alpha particle can travel no more than one to three inches in the air before stopping, and can be stopped by a piece of paper. However, they can pass through a thin mica window. mica is very important in radiation measurements.
Beta particles can damage skin, however, both alpha and beta radiation are most harmful when inhaled or ingested.
