What is the purpose of shielding in radiation work?

The purpose of shielding in radiation work is primarily to reduce radiation exposure by blocking or absorbing radiation. When working with radioactive materials or radiation-producing equipment, it is essential to protect personnel and the environment from the harmful effects of ionizing radiation. Shielding provides a physical barrier between the radiation source and individuals, effectively lowering the radiation dose that could be received.

Different materials can be used for shielding depending on the type of radiation being encountered (like alpha, beta, gamma, or neutron radiation). For example, lead is commonly used for gamma radiation shielding because of its high density, while plastic or glass may suffice for beta radiation. By strategically placing these materials around the radiation source or in the vicinity of workers, radiation exposure can be significantly mitigated, promoting safety and health among personnel in radiation-related fields.
