Which principles are usually applied to radiological incidents and chemical agents?

The principles that are commonly applied in dealing with radiological incidents and chemical agents focus on minimizing exposure and protecting responders and the public. These principles are time, distance, and shielding.

When addressing a radiological incident, every effort is made to limit the time spent in contaminated areas to reduce exposure to harmful radiation. The principle of distance plays a crucial role as well; increasing the distance between oneself and the source of radiation significantly decreases the amount of exposure received due to the inverse square law of radiation. Lastly, shielding involves using barriers, such as walls or specially designed protective gear, that can absorb or deflect radiation, providing an additional layer of safety.

In this context, the correct answer aligns with the established practices in the field of emergency response to radiological and chemical hazards, emphasizing safe operational protocols that prioritize human health and safety.
