Nuclear radiation refers to radiation produced by particles or electromagnetic waves emitted by radioactive substances. The nuclei of atoms in radioactive materials are unstable and will spontaneously undergo radioactive decay, releasing energetic particles or electromagnetic waves. This nuclear radiation has strong penetrating power and energy, and can cause radiation damage to living organisms and substances. Nuclear radiation has potential hazards to human health, including radiation sickness, genetic mutations, cancer, etc.

Nuclear radiation refers to the phenomenon of radiation produced by particles or electromagnetic waves emitted by radioactive substances. The nuclei of radioactive materials are unstable, so they spontaneously undergo radioactive decay, releasing high-energy particles or electromagnetic waves. These particles or waves can penetrate air, objects, and tissues, causing radiation damage to living organisms and substances.
There are three main forms of nuclear radiation: α particles, β particles, and γ rays. α particle is a positively charged particle composed of two protons and two neutrons, which has a lower energy and a weaker penetrating ability, but has a greater interaction in matter. β particles are negatively charged high-speed electrons or positrons with higher energy and stronger penetrating ability. γ rays are high-energy electromagnetic waves with the highest energy and the strongest penetrating power.
Nuclear radiation is potentially harmful to human health. When nuclear radiation interacts with living organisms, it interacts with molecules in cellular tissues, leading to DNA damage, cell death, and mutations. These injuries can lead to the development of diseases such as radiation sickness, genetic mutations, and cancer.
In order to control and protect the hazards of nuclear radiation, a series of protective measures have been taken. In the nuclear industry and medical field, protective shielding materials are used to reduce the penetration of nuclear radiation, appropriate protective equipment such as lead clothing, protective glasses, etc., warning signs and restricted areas are set up near radiation sources, and radiation levels are regularly monitored and measured.
Nuclear radiation is a radiation phenomenon produced by particles or electromagnetic waves released by radioactive substances, which has strong penetration and energy, and is potentially harmful to human health. Therefore, the control and protection of nuclear radiation is of paramount importance.
