Neutron Putty | JCS Nuclear Solutions

JC261 Neutron Putty can be used for the collimation of neutrons and for reducing neutron streaming.

It is a non-hardening, boron loaded LDPE 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.

Features at a glance

Neutron Putty contains 10% boron and high hydrogen content.
A 1-inch thick layer has a thermal neutron attenuation factor of approximately 100
Since Neutron Putty is non-hardening, it will not dry out to form a powder
Provided in 8lb (3.6 kg) cans
