  • Title: Practical low dose limits for passive personal dosemeters and the implications for uncertainties close to the limit of detection.
    Author: Gilvin PJ, Perks CA.
    Journal: Radiat Prot Dosimetry; 2011 Mar; 144(1-4):102-6. PubMed ID: 20959337.
    Abstract:
    Recent years have seen the increasing use of passive dosemeters that have high sensitivities and, in laboratory conditions, detection limits of <10 µSv. However, in real operational use the detection limits will be markedly higher, because a large fraction of the accrued dose will be due to natural background, and this must be subtracted in order to obtain the desired occupational dose. No matter how well known the natural background is, the measurement uncertainty on doses of a few tens of microsieverts will be large. Individual monitoring services need to recognise this and manage the expectations of their clients by providing sufficient information.
