註釋
A radiation monitoring programme was carreid out at Kvanefjeld, South Greenland, with the aim of estimating the level of external radiation exposure to personnel working in this area that has elevated background radiation levels because of extensive uranium and thorium mineralizations. The measuring programme included 1) environmental monitoring with TL dosimeters, high pressurized ionization chamber, and plastic scintillometer, and 2) personnel monitoring with TLD badges of drillers and geologists during their survey programme. A geological description of the area is given and results from the different methods of measurement are compared. The radiation exposure level data that were recorded make it possible to estimate the external personnel gamma radiation doses which may be obtained during future field work at Kvanefjeld. The annual personnel dose is calculated to amount to a maximum of 1.3 rad.
