Neutron dosimetry | Neutrak | Models | CR-39 technology | HSE Approvals

Our two types of Neutrak offer a wide range of energy measurements.

> Neutrak 144-J

> Neutrak 144-T

Neutrak 144 - J is our standard for intermediate and fast neutron monitoring. This detector uses a polyethylene radiator for fast neutrons, recoil protons resulting from neutron interactions in the dosemeter produce damage tracks in the CR-39 detector. It is wrapped in a white label.
This detector is particularly adapted to: Americium / Beryllium containing equipment such as a gamma densitometer, nuclear fuel production facilities.

Energy and doses ranges

	Energies detected	Minimum exposure range	Maximum exposure range
Neutrak 144-J	40 keV to 40 MeV	0.20 mSv	250 mSv

Neutrak 144 – T is developed for fast, intermediate, and thermal neutrons. The left area of the chip uses a polyethylene radiator for fast neutrons. The right area uses a boron loaded Teflon^® radiator that also records alpha particle produced by the interaction of thermal neutrons with the boron radiator. It is wrapped in a yellow label.
