LB134N Neutron Dose Rate Meter

Neutron Dose Rate Meter

Product introduction

The system probe adopts the patented He-3 proportional counter tube. The counter tube is placed in the center of the moderator sphere with a diameter of 250mm. The geometric position of the counter tube is calculated according to the Monte Carlo simulation program (MCNP) and has obtained a patent. The instrument has a fairly high sensitivity of about 3 counts per nSv, making it ideal for measurements in very weak neutron radiation fields. It can be used as a portable dosimeter or as a fixed dose monitor. The monoenergetic neutron fluence response experiment was carried out at the Braunschweig Institute for Physics in Germany.
