- •
Supplied water in semiarid region was analyzed concerning heavy metals, cyanobacteria and radiation.
- •
Indoor radon and gamma emitters (U, K and Th) concentrations were measured.
- •
High radon levels are present inside urban residences.
- •
It was found high frequencies of micronuclei and nuclear alterations in human oral mucosa.
- •
High background radioactivity could explain the observed mutagenic effect observed.
