Newlife specializes in the research of high-energy ray absorbent and lead-free shielding materials for more than 10 years. Our γ-ray protective core material is a light weight, flexible and eco-friendly, aimed for nuclear energy and nuclear emergency preparedness. It is composed of γ-ray absorber and polymer material, which can effectively replace traditional lead board and rubber materials. For radioisotope sources such as Am241, the weight of our ALF series can be reduced by more than 30% than that of traditional lead rubber with the same protection effect under 100Kev.
