Students have asked these similar questions
Often, when people have to work around radioactive materials spills, we see them wearing white coveralls (usually a plastic material). What types of radiation (if any) do you think these suits protect the worker from, and how?
2. The intensity of radioactivity depends on the distance of the recipient from the source of radiation and follows an inverse square law. Suppose an object receives 1,230 millirem of radiation when it is 10 m from the source, calculate the distance if the object is now exposed to 350 millirem.
4.What are beneficial applications of radiation?
Select two that apply.
1.Radioactive nuclides are used to power objects such as rocket engines.
2.Radiation treatments are used to kill cancer cells.
3.Radiation treatments are used to examine tissue under microscopes and make diagnoses.
4.Radioactive nuclides are used to date rocks and artifacts.
