[en] The ambient and individual monitoring of workplace neutron fields is frequently performed with neutron dosemeters relying on nuclear track detectors, especially poly-allyl-diglicol-carbonate (PADC). Nevertheless, such systems are usually unable to measure doses below 100-200μSv, due to the large variability of the background in the plastic materials. This constitutes a relevant limitation in those practical scenarios where the optimization procedures require compliance with very low dose constraints, such as few hundreds of μSv in one year. With the aim of providing better dosimetric performance for radiation protection purposes around the DAΦNE accelerator, a new dosimetry system was developed by the Radiation Protection Group of the INFN-LNF. This work describes a new four element dosemeter, whose main characteristic is a detection limit lower than 50μSv. Details are given of the dosemeter, the analysis procedure, the background and the performance in the field of low doses. The system is already in operation for the routine area monitoring of the INFN-LNF site
