Radon mapping of soils in St. Elizabeth, Jamaica

Soil gas measurements of radon were made in St. Elizabeth, Jamaica using nu clear track etch detectors. The results were compared to gamma-ray spectros copy measurements made in the laboratory on soil samples collected at the r adon measurement sites. An assessment of the degree of disequilibrium of ur anium and thorium was also made by comparison with neutron activation analy sis, delayed neutron counting and equivalent uranium and thorium measuremen ts. The results to date for equivalent uranium and radon show a strong corr elation and indicate the possibility of soil radon mapping in Jamaica using gamma-ray spectroscopy. Three anomalous sites have been identified.
