Annual background radiation in Chaharmahal and Bakhtiari province

Background: Measurement of background radiation is very important from different points of view especially for human health. The aim of this survey was focused on determining the current background radiation in one of the highest altitude regions ( Zagros Mountains ), Chaharmahal and Bakhtiari province, in the south west of Iran .

Materials and Methods: The outdoors-environmental monitoring exposure rate of radiation was measured in 200 randomly chosen regions using portable Geiger-Muller and Scintillation detectors. Eight measurements were made for each region and an average value was used to calculate the exposure rate from natural background radiation.

Results: The exposure dose rate was found to be 28.4 m Rh^-1 and the annual average effective equivalent dose was found to be 0.49 mSv. An overall population weighted average outdoor dose rate was calculated to be 49 nGyh^-1, which is higher than the world-wide mean value of
44 nGyh^-1 and is comparable to the annual effective equivalent dose of 0.38 mSv.

Conclusion: A good correlation between the altitude and the exposure rate was observed, as the higher altitude regions have higher natural background radiation levels. Iran . J. Radiat. Res.; 2003; 1(2): 87 – 91….”

And while they looked for the causes of cancer in the below study they found two main contributing (alleged) factors, consanguineous marriage and altitude/radiation exposure.

Pancreatic Cancer: State of the Art and
Current Situation in the Islamic Republic of Iran

Govaresh\ Vol. 14, No.3, Autumn 2009; 189-197

“…Most of these provinces
including Khorasan, Hormozgan, Chaharmahal
and Bakhtiari, Ilam, and Kohkiloueh and
Boyerahmad are among the provinces with high
rate of consanguineous marriage in Iran (12,13).
Other environmental factors may also be
associated with the higher rate of pancreatic
cancer in these provinces as Chaharmahal and
Bakhtiari and Kohkiloueh and Boyerahmad are
two provinces close to each other in the
surrounds of Zagros mountain range. People
living in these two provinces have many cultural
characteristics and behavioral habits in common…”

an interesting study as the west is generally looking at alcohol as the main cause now because the “virus” theory has no proof after 20 years..

NOTE : there is no research into radiation causing cancers this year as Prof C Busby nor any independent researcher is getting any funding.. and the budget has tripled this year for R and D in cancer.. Arclight
