Abstract: (8248 Views) |
Editor, I read the recent publication by Toossi et al. with a great interest (1). Toossi et al.
concluded that “Average gonad and bone marrow doses for North Khorasan, Boshehr and
Hormozgan provinces were less than the corresponding values for normal area (2).” There are
some facts on this report to be concerned. I agree that the detected levels might be high in
the mentioned area, but the problem is whether this high dosage is an actual problematic
phenomenon. First, the selection on small sites and samplings within a short period might
not provide a good representative data on the actual situation in that area. Second, the
difference in time of sample collection among different sites might contribute to difference in
detected levels. The variation of the atmosphere might be a big factor to be mentioned.
Third, the detected levels might not directly imply the risk for the people living in those
areas since the people do not statically but dynamically lives from places to places.
