from 200 ppm for A to 500 ppm for X, as shown in table 1.
According to the International Atomic Energy Agency
(IAEA) and the World Health Organization (WHO), the
results demonstrate that the concentration of all elements,
except uranium, on the soil sample is within the permissible
range. Uranium concentrations in soil samples ranged from
0.024236 to 0.23439 ppm, while in water and plant samples
they were 0.024705 ppm, with a safety limit of 0.03 ppm.
