Use of TASTRAK in Neutron Dosimetry

TASTRAK is sold worldwide for use in fast neutron and thermal neutron dosimetry.

One of the most exacting applications for plastic track detectors is in the field of neutron dosimetry.  Fast neutrons are detected by recording tracks of recoil protons, generated either in the etchable volume of the plastic itself, or in an overlying radiator.  The spectrum of recoil protons from typical fission neutrons is dominated by low energy, low angle small penetration tracks in the plastic. Reliable measurement of the spectrum of the resultant etch tracks requires high quality material with the lowest level of background and the highest level of reproducibility in response. 

 Our system uses sophisticated image analysis routines which can discriminate between etched tracks and background objects, and can characterise each object which it identifies with multiple parameters.  This enables the system to function using a single etch only - the system can produce accurate low background results without the use of a deleting etch.  This means that a methanol pre-etch is NOT required.  

TASTRAK has been designed specifically with these exacting requirements in mind and is used widely in neutron dosimetry applications.

Thermal neutrons may be detected by use of an overlying boron-rich radiator, recording thermal neutron by the n(¹⁰B,³Li)a reaction.  We manufacture carborane-doped (B₁₀H₁₀C₂H₂) TASTRAK, suitable for use as a thermal neutron radiator.
