Ohm's law
Cannot penetrate most matter. A piece of paper or the outer layers of skin is sufficient to stop these particles. If consumed, inhaled, swallowed, or absorbed into the bloodstream through wounds can lead to harm.
Alpha particles
Gamma Rays and X-Rays
Beta particles
Acute Radiation Syndrome (ARS)
Can be stopped by a layer of clothing or a few millimeters of a substance such as aluminum. Capable of penetrating the skin and causing radiation damage such as skin burns.

Acute Radiation Syndrome
Symptoms of short-term radiation effects after a massive dose of ionizing radiation. Occurs in extreme circumstances. Must reach internal organs. Symptoms may include skin burns, nausea, vomiting, loss of appetite, fatigue, fever, diarrhea, seizures, and/or coma.
