Study Notes
Radiation Safety
- Activities involving radiation require safety standards.
- These include medical uses, operation of nuclear installations, production, transport, use, and management of radioactive waste.
- Exposure to radiation must be evaluated and controlled to ensure safety for workers, the public, and the environment.
Ionizing Radiation
- Ionizing radiation has enough energy to remove electrons from atoms, causing them to become charged or ionized.
- It is generated due to energy changes in an electron.
- X-rays and gamma rays are similar and are emitted when an electron transitions from a higher energy level to a lower energy level, releasing excess energy.
- Neutron radiation is different and consists of free neutrons, usually emitted during nuclear fission (either spontaneous or induced).
- Neutrons are indirectly ionizing. They are absorbed into stable atoms, making them unstable and more likely to emit other types of ionizing radiation.
