People who work with radioactivity
must always take the necessary safety precautions.
What Safety Precautions are Needed when Working with Radioactivity?
Safety Precautions in School.
that are used in school are usually very
They can only be used in the presence of an authorized teacher.
They are kept in a sealed container except when they are being used

to prevent any penetration by alpha particles or beta particles.
that are operated by remote
control can be used to
deal with very contaminated areas or high intensity gamma emitters.
