The demand for high density (heavyweight) concrete shielding in hospitals continues to grow. 

Shielding is required in hospitals and cancer clinics from radiation sources which commonly include linear accelerators and cyclotrons.

NSS regularly works with hospital physicists and architects to supply them with information on high density (heavyweight) aggregates, mix designs and technical expertise for their shielding requirements.

At an increasing rate, hospitals are steering clear of negative environmental and health issues associated with lead and are discovering high density (heavyweight) concrete as the all-in-one, environmentally safe radiation shields.
