Neutron Dosimetry
LB Servizi is one of the few dosimetry laboratories in Italy capable of offering a dosimetric system for environments with exposure to neutron radiation.
The thermal neutron dosimeter consists of an outer casing with appropriate differential filtration between the part facing the radiation field and the rear part, and two sensitive elements: a LiF (Mg, Cu, P) – GR200A detector and a LiF (Mg, Cu, P) – GR207A detector.
Our specialized expertise sets us apart, enabling us to deliver highly accurate neutron-exposure assessments through the use of advanced technologies and state-of-the-art procedures.
The sensitive material of the fast neutron dosimeter is an organic polymer made of Poly Allyl Diglycol Carbonate (commercially CR-39), placed on a 1 mm thick plastic support. Interaction of incident neutron radiation with the material produces charged particles, alpha particles, and recoil protons, which create structural damage (tracks) along their path within the polymer.
A chemical etching process makes the tracks visible using digital scanners. Counting the tracks on the material, after proper calibration, allows the evaluation of the relevant dosimetric quantities.
Dosimeters can also be used in multiple configurations, combined with TL dosimeters for thermal neutron radiation, within the same packaging.
