How can radiation be prevented or contained?

Radiation can be prevented or contained through various methods, including shielding, distance, and containment. Shielding involves using materials like lead or concrete to block radiation; increasing distance from the radiation source reduces exposure. Containment strategies, such as using sealed containers or specialized facilities, help prevent the release of radioactive materials into the environment. Additionally, strict regulatory measures and monitoring can ensure safe handling and disposal of radioactive substances.
