Some authors reported finding high levels of radioactivity in moderately saline confined aquifer water in various parts of the Disi area (South East of Jordan), and they suggested more research into the effects of that water on irrigated soils. 28 surface and subsurface soil samples from five profiles, together with five well water samples (used for both irrigation and drinking), were taken from that location for this investigation. Currently, the production of inorganic P fertilisers from a limited supply of rock phosphate is necessary to maintain the world's food supply (RP). Phosphogypsum (PG), a byproduct of the manufacturing of P fertilisers from RP, is so radioactive that its re-use is prohibited even though it is a substantial contaminant in and of itself.

This analysis is useful for determining the correlations between radiological hazard parameters and radionuclides, which helps in determining the public's potential health exposure to the examined soil. The amount of radioactivity in the water is primarily from 226Ra, and the total radioactivity in deep groundwater was higher than that in shallow groundwater. Additionally, for shallow groundwater samples, the effective doses for ingesting natural radionuclides were around 0.333 mSv y1 and approximately 1.338 mSv y1 for deep groundwater samples.
