Explanation:
Detailed explanation-1: -Lead aprons or vests. Wearing lead aprons can reduce a worker’s radiation dose. Customized lead (or lead equivalent) aprons are available for a wide range of occupational settings and job tasks. A lead apron is only effective when it is worn properly and provides adequate protection necessary from the radiation source.
Detailed explanation-2: -Distance: Just as the heat from a fire is less intense the further away you are, so the intensity and dose of radiation decreases dramatically as you increase your distance from the source. Shielding: Barriers of lead, concrete, or water provide protection from penetrating radiation such as gamma rays and neutrons.
