|Abstract:||At the Radiation Protection Laboratory of the INFN¿Frascati National Laboratories, a new polyallyl diglycol carbonate (PADC) based fast neutron dosimetry system has been established for the routine monitoring of ambient neutron radiation around the 510MeV e+/e- DAØNE collider as well as research activities in the field of neutron dosimetry. The detectors, supplied by Intercast (Parma, Italy), are processed by means of a two-stage chemical etching. The analysis is performed with a new automated reader, developed at the laboratory under the Labview (National Instruments) environment. Taking advantage of a set of automated motion, vision and regulation procedures, this system provides very reproducible, accurate and quick results suitable for both investigation and routine purposes. Moreover, the adoption of a four element configuration combined with a deep study of the background distribution, allows obtaining a minimum detectable ambient dose equivalent as low as 30µSv. This work analyzes the dosimetric performance of the LNF ambient dosemeter as well as the characteristics of the LNF new reading system.|
