MODEL JC258
Description:
Neutron sources such as Cf, Am-Be and Pu-Be require transporting in specialist shielding casks. Model JC258 is designed for this purpose. These casks are designed to be moved by fork lift or overhead lifting device.
The casks are ruggedly constructed of heavy gauge steel, using Polycast JC259 as the shielding material, which has an exceptionally high hydrogen content. There is a central lead cup to shield against primary gammas and 0.9% boron to absorb thermal neutrons and suppress secondary gamma dose. The casks can be qualified as DOT Type 'A' shipping containers.
