原始语种摘要: Total reliance onquarry products as construction materials has prompted commercial quarryactivities globally. However, potential risks introduced by radiation exposureto quarries in two different locations in Ondo State, Nigeria were assessed toevaluate the background radiation and distribution of naturally occurringradionuclides associated with these areas. A ground radiometric mapping ofeleven traverses across the two quarry sites was carried out using Gamma rayspectrometer. Naturally occurring radionuclides 238U, 232Thand 40K in natural quarried materials of coarse rock aggregates andsoil samples collected at a maximum depth of 2 m and up to 500 m away from thequarry sites were measured using gamma spectrometry method. Spectrometric datawere processed...
