In the absence of permanent rivers or bodies of water, half of the Saudi Arabia domestic water consumption is provided
through desalination. The other half is derived from groundwater. Groundwater from the Disi aquifer is already used for drinking
water in parts of Jordan and, more extensively, in Saudi Arabia, where it is known as the Saq aquifer. Some of the geological
analyses of the host sandstone aquifer rocks show 228Ra and 226Ra. The usefulness of chromosomal aberrations
analysis as a bioindicator for ionising radiation effect was tested in underground water well workers of Saudi Arabia in this
industry producing technologically enhanced naturally occurring radioactive material. The incidence of chromosomal aberrations
was evaluated using the metaphase analysis method in the lymphocytes of peripheral blood of 10 persons working in
underground water well. The age range of the workers was 25–40 y and their duration of service ranged from 3–7 y. For comparison,
blood samples were also collected from 10 subjects (controls) who belonged to same age and socioeconomic status.
Subjects in the both groups were non-smokers and non-alcoholics. Results showed that the mean frequencies of dicentrics and
acentrics in underground water well workers are significantly higher than those in controls. The higher frequency of chromosomal
aberration in lymphocytes of underground water well workers compared with controls could be due to the accumulative
effect of radiation. The results of this study demonstrated that occupational exposure to radiation leads to a significant induction
of cytogenetic damage in peripheral lymphocytes of workers engaged in underground water well.
