Abstract
The concentration of 238U, 232Th and 40K in rock samples were analysed using gamma ray spectrometry. In Kubwa, the concentration ranges from 15 to 52 Bq kg-1 for 238U, 32 to 84 Bq kg-1 for 232Th and 119 to 705 for 40K Bq kg-1. In Gosa area, the concentration of 238U ranges from 23 to 30 Bq kg-1, 232Th varied from 48 to 76 Bq kg-1, and 40K varied from 438 to 820 Bq kg-1. The dose rate, radium equivalent activity and annual effective dose rate at Kubwa and Gosa were calculated and compared with international standard values.
