Russian enterprise develops borated polyethylene material for neutron radiation protection

A neutron radiation protection material developed by Russian company NPO Gelar has obtained relevant certification. The material, named Polikeramoplast-PB, is a borated polyethylene that resembles ordinary gray or black plastic sheets in appearance, but its protective performance derives from the combination of hydrogen and boron.

According to reports, the hydrogen in the material effectively moderates fast neutrons, reducing the likelihood of subsequent secondary reactions, while the boron helps absorb moderated neutrons. In contrast, traditional heavy metal materials used for gamma-ray shielding are not suitable for standalone neutron protection, as heavy atomic nuclei have limited attenuation effects on neutrons.

The material can be used in radiation therapy room protection systems and combined with lead or steel. In this setup, lead or steel primarily absorbs the gamma-ray component, while the borated polyethylene handles neutron radiation protection, forming a more comprehensive composite shielding solution.

Data also shows that the region where the relevant enterprise is located is one of the faster-developing areas within the ZATO, currently hosting 28 enterprises managed by Atom-TOR. The region has announced investments exceeding 1 billion rubles and has created over 350 new jobs.
