Final answer:
True, in events involving radioactive spills, moving to the outer perimeter, alerting others, and contacting the Radiation Safety Office are appropriate safety measures. These actions help contain and mitigate the situation, while evacuation zones protect the public.
Step-by-step explanation:
For large spills/incidents/accidents involving radioactive material, one should indeed move to the outer perimeter of the immediate area, alert others to prevent the spread of contamination, and contact the Radiation Safety Office. Following these steps minimizes exposure and allows for professionals to manage the situation effectively. Experienced personnel will determine the necessary procedures for decontamination, establish an evacuation zone based on radiation levels, and provide personal protection equipment to workers, such as white coveralls, to protect against particulate contamination.
In the event of a nuclear accident, like the 2011 earthquake in Japan, establishing a clear evacuation radius is crucial to safeguard the population from radioactive fallout. Moreover, special attention is needed to prevent the contamination of the food chain, which can affect all levels from microscopic organisms to humans and lead to widespread environmental and health issues. The cost of such accidents goes far beyond the immediate financial impact, often contributing to long-lasting ecological and societal costs.
