What are the protective measures for radioactive material?

The protective measures for radioactive material primarily focus on time, distance, and shielding, which are fundamental principles in radiation protection.

Time refers to minimizing the duration of exposure to radioactive sources. The less time spent near a radioactive material, the lower the overall radiation dose received.

Distance plays a crucial role as radiation intensity decreases significantly with increased distance from the source. By maintaining a safe distance, individuals can significantly reduce their radiation exposure.

Shielding involves using materials that absorb or block radiation to prevent it from reaching individuals. Common shielding materials include lead, concrete, and other dense substances that can effectively stop or reduce radiation levels.

While evacuation and sheltering can be essential in certain emergency situations involving radioactive materials, the concepts of time, distance, and shielding offer ongoing, practical strategies for protecting individuals from radiation in various scenarios. Other options like face masks and gloves primarily provide protection from physical contaminants rather than directly addressing the specific nature of radioactive exposure. The option mentioning high altitude and low exposure does not reflect standard safety measures associated with managing radiation risks.
