Neutron & Gamma Putties

Boron Neutron Putty

Neutron Putty is readily pliable, yet has enough consistency to hold its shape after placement, requiring no special tools or techniques to create a neutron shield in an irregular space. Neutron Putty can be used for collimation of neutrons and for neutron streaming.  It is a non-hardening, reusable, boron loaded putty.

It contains 10% boron and has a high hydrogen content to slow fast neutrons to thermal neutrons.  It is readily available in 8-lb (3.6kg) cans and has a density of 1.1 g/cc (69 lbs/ft³).
