Neutron Putty Radiation Shielding

 

 Introduction

 

●  Used For Collimation of Neutrons and Neutron Steaming

●  Contains 10% Boron and High Hydrogen Content

●  Non-Hardening, Will Not Dry Out, Provided in 8 lb Cans

 

Shieldwerx SWX-261 Neutron Putty radiation shielding can be used for the collimation of neutrons and for neutron streaming. It is a non-hardening, boron loaded putty that contains 10% boron combined with a high hydrogen content. Neutron Putty can be kneaded by hand to obtain the desired consistency and workability. It can be softened by warming it up slightly for added workability. Disposable gloves are recommended when handling as the putty is quite sticky. A 1-inch thick layer of Neutron Putty has a thermal neutron attenuation factor of approximately 105.
