NPO EUROPE uses many types of neutron absorbtion materials such as polyethylene, borated polyethylene and naphthalene to thermalize and capture neutrons.

 

Polyethylene

The hydrogen contained in the polyethylene thermalize significantly neutrons .

 

Borated polyethylene

Another rapid neutrons absorption material is to add boron in the polyethylene

The probability of neutron capture by a boron is more than 10,000 times that of a hydrogen nucleus, regardless of the neutron energy. The probabilities themselves increase significantly when the neutron is thermalized hydrogen).

Borated polyethylene shields are perfect for reducing neutron dose in a general area.

Borated polyethylene is incorporated in NPO shield bells, lid shields, and other applications where neutron radiation is the biggest concern.

 

T FLEX® (tungsten / bismuth / iron) + boron.

A combination of benefits! Our T-FLEX® is an excellent attenuator for gamma radiation. We can add to our matrix boron to make a neutron shielding as well.
