The possibility of using the specific responses of the high temperature Peaks 6 and 7 and Peaks 4 and 5 to different LET radiations was mentioned in the past mainly for very high doses. The applicability of the two regions method for thermal neutrons - gamma ray mixed field dosimetry was investigated by analysing the response of LiF:Mg,Ti dosemeters irradiated to different ratios of thermal neutrons and gamma rays at radiation protection dose levels encountered in routine work conditions, up to ∼50 mSv. The Region of Interest method was used to define the areas of the Peaks 4+5 and 6+7. We found that a simple algorithm can be used to determine with good accuracy the separate contributions of neutron and gamma doses.
