Radiation protection is one of the primary concerns in a nuclear power plant. Progress is being made on a yearly basis in terms of the doses that may be received. Notably thanks to the processes that enable this dose to be reduced at the source. For this very reason, Pronal has designed a range of biological protection stoppers that effectively creates a protective barrier for workers. These flexible barriers are then filled with water. When filled to a thickness of 200mm, the stoppers are as equally effective as a 50mm lead cushion. The ease with which these biological barriers can be installed and removed makes them a more practical choice than working with lead cushioning. The dimensions and forms of these biological barriers can be defined based on the client’s specifications. Indeed, thanks to our engineering office, we can make tailor made products. Finally, our biological protection stoppers are in full compliance with the ALARA principle; the core principle outlining protective measures against ionizing radiation.
