When the atomic nucleus undergoes beta decay, it is releasedBeta rayAnd beta ray is the high-speed electron flow.
Electrons moving at high speed will be affected by electromagnetic field due to negative charge.Its volume ratioAlpha particleIt is much thinner, and its penetration ability is stronger than that of alpha particles. It requires an aluminum sheet several millimeters thick to block it.Many radioactive substances will be released during decayBeta particle。

Electron flow
Beta ray is a kind of charged high speed running secondary nuclideRadioactive decayThe stream of electrons released from.Human beings are exposed to β - rays from man-made or natural sources (tritium, C-14, etc.), β - ray ratioAlpha rayIt is more penetrating, but it causes less damage when passing the same distance.someBeta rayIt can penetrate the skin and cause radiation injury.But once it enters the body, it will cause more harm.
Beta particleIt can be cut off and blocked by external clothes or completely blocked by a piece of aluminum foil several millimeters thick.
