On The Source Radiation Shielding
Overview
When possible, installing radiation shielding directly on the source of radiation is the best solution. On the source radiation shielding requires less shielding material than general area radiation shielding which saves on installation time and cost. Shielding the source of radiation can allow down-posting of Locked High Radiation Areas (LHRA) or High Radiation Areas (HRA) which alleviates a significant administrative burden from the Radiation Protection (RP) department and improving overall efficiency of plant operations in the area.
Several types of NPO on the source radiation shielding are specially designed for installation directly on the radiation source. Our T-Flex product is flexible and can be manufactured to perfectly fit any component. Common T-Flex products designed for direct application to the source include pipe radiation shields, ribbon wrap, valve radiation shields, and magnetic tiles. NPO utilizes 3D printing technology to create molds that allow T-Flex to embody practically any 3D shape.
