摘要：
Soil radon and the gamma-dose rate have been determined along the Guerrero coast of Mexico, using track detectors, LR 115 Type II and thermoluminescent CaSO4:Dy detectors. Mineralogical analyses were done and Ra-236 and K-40 specific activities were measured in the rock samples. The results indicate a good correlation between the response of average gamma-dose rate versus radon concentration in the soil. Differences in the radon levels, in the activity concentrations in the rocks and in the local seismicity defined two geographical zones where the number of seismic events, the average radon and the average gamma-dose rate were correlated.
