Investigation of natural gamma radiation dose rate (GDR) levels and its relationship with soil type and underlying geological formations in Jordan

Measurement of gamma radiation dose rates based on soil types and geological formations was carried out as a pioneer study in Jordan extensively. 823 measurements were taken at 1 m above the ground using two survey meters (Inspector Alert manufactured by S.E. International and Radiagem, 2000 Geiger...
