摘要：

Uranium and thorium contents as well as radon and thoron a-activity concentrations were evaluated inside different underground water samples by using a method based on calculating the CR-39 and LR-115 type U solid state nuclear track detectors (SSNTDs) detection efficiencies for the emitted alpha-particles and measuring the resulting track density rates. The validity of the SSNTD technique utilized was checked by analysing uranium nitrate standard solutions. A relationship between water radon concentration and recharge of wells dug in two Moroccan Atlantic coastal regions, for a given Lithology, was found. The influence of the lithology and depth on radon concentration and salinity of well waters studied was investigated.
