Question

State any two precautions to be taken while handling radioactive substances

Advertisements

Solution

The two safety precautions to be taken while handling radioactive substances are (any two):

  • Radioactive substances should be kept in thick lead containers with a very narrow opening so as to restrict the radiations coming out from other directions
  • Radioactive materials should be handled with long lead tongs.
  • People working with radioactive substances should put on special lead-lined aprons and lead gloves
