Abstract: Radiometry techniques were applied to evaluate the activity and concentration values of ²³⁸U, ²³²Th and ⁴⁰K in four types of Egyptian made fertilisers. Also, radon and thoron concentration values were estimated for the same samples. The Hyper-Pure Germanium Detection System (HPGeDS) installed at the hot laboratories of Inchas, Cairo, and the Solid State Nuclear Track Detection System (SSNTDS) facility of the Girls| College were used for measurements. A comparative study on the concentration values obtained in this work for the four fertiliser samples is presented.

Keywords: radon estimation; thoron estimation; natural radioactivity; Egypt; organic fertilisers; chemical fertilisers; low radiation; HPGe.
