Ionizing radiation includes particles and rays with enough energy to ionize atoms.

This device detects ionizing radiation such as alpha and beta particles.

Gamma rays can penetrate most materials and require dense shielding.

Rem or sievert are commonly used to measure equivalent dose.

It uses a scintillating material to emit light when struck by radiation.

Alpha particles can be stopped by a sheet of paper or skin.

It helps monitor exposure and ensures safety.

Half-life is the time for half the atoms to decay.

Dosimeters track cumulative exposure over time.
