  • Title: Occupational radiation exposure to norms in a gold mine.
    Author: Darko EO, Tetteh GK, Akaho EH.
    Journal: Radiat Prot Dosimetry; 2005; 114(4):538-45. PubMed ID: 15914510.
    Abstract:
    Preliminary studies have been conducted into the occupational radiation exposure to NORMS from surface and underground mining operations in a gold mine in the Ashanti Region of Ghana. A brief description of the methods and instrumentation is presented. The annual effective dose has been estimated to be 0.26 +/- 0.11 mSv for surface mining and 1.83 +/- 0.56 mSv for the underground mines using the ICRP dose calculation method. The results obtained are found to be within the allowable limit of 20 mSv per annum for occupational exposure control recommended by the ICRP.
