Lead is used in various industries for protection from the harmful effects of radiation. The latest imaging techniques  used in the diagnosis and treatment of cancers, degenerative disorders and other illnesses, could not be carried out without lead protection for the patients and medical staff.  Calder are suppliers of isotope pots, hot cells, lead bricks and other products used in the medical industry.

Research scientists use lead lined rooms, lead plates, lead blankets, lead shot and complex cast items to protect themselves from radiation during their work.

The defense industry uses lead shielding such as bricks  and plates for shielding of reactors on nuclear powered vessels.

Nuclear power can not be produced without lead radiation shielding for reactors and waste management.
