What is one of the means of managing radiation exposure?

Waiting for radioactive material to decay is a widely recognized method for managing radiation exposure. This approach is based on the principle that all radioactive materials have a certain half-life, which is the time it takes for half of the radioactive atoms to decay into a stable form. By allowing time to pass, the level of radioactivity in a given material diminishes as the radioactive isotopes decay, thereby reducing the potential radiation exposure to individuals.

This method is particularly useful in situations where immediate removal or containment of radioactive materials is not feasible. It allows for a natural reduction in hazard levels, making environments safer for human interaction or for conducting work related to those materials.

Other options like consuming water, daily exercise, or using heavier tools do not directly relate to the management of radiation exposure in a scientifically established way. While hydration and physical health are important for overall well-being, they do not specifically mitigate or manage the risks posed by radiation exposure, nor do they influence the decay of radioactive substances.
