  • Neutron Putty contains 10% boron and high hydrogen content

  • A 1-inch thick layer of Neutron Putty has a thermal neutron attenuation factor of approximately 105

  • Since Neutron Putty is non-hardening, it will not dry out to form a powder

  • Provided in 8 lb. (3.6 kg) cans

 

Introduction

 

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.
