3. Results and Discussion

Thespecific activities of ²²⁶Ra, ²³²Th, and ⁴⁰Kin commonly used fertilizer samples in Egypt and Japan are given inTables 1 and 2. The respective average radionuclide activities of ²²⁶Ra, ²³²Th, and ⁴⁰K in the Egyptian fertilizer samples were  571+-20 Bq kg⁻¹, 19+-5  Bq kg⁻¹, and 182+-40  Bq kg⁻¹ while, for the Japanese fertilizers, they were 325+-2  Bq kg⁻¹, 9+-1  Bq kg⁻¹, 1500+-10 and  Bq kg⁻¹, as shown in Figure 1 and Tables 1 and 2. The radionuclide concentrations in Japanese fertilizer were less than those of Egyptian fertilizers except for potassium, as seen in Figure 1. The radionuclide concentration of ⁴⁰K is much higher in Japanese fertilizer samples and especially sample JF-1. Both Egyptian and Japanese fertilizers maintain radionuclide concentrations less than the recommended limits by UNSCEAR, 2008, [22].
