The Map of the Natural Radioactivity of the Absheron Peninsula (completed, 1996)

Scale 1:200,000 (1996)


SUMMARY


The map of the natural radioactivity shows the space gamma-radiation distribution and contains valuable data on radioactivity distribution on the Absheron peninsula with geological structure, tectonical activity and technogenic environment pollution by radionuclides of natural origin.


The Absheron peninsula is composited by weakly radioactive sedimentary rocks, presented by clays, sands, limestones, that is why radioactive background fluctuates here 6 mkR/h (50n Gy/h) that is the most favourable environments for human living. On the coast, composited by seasnd, radioactive background decreases up to 3 mkR/h, on separate area (above the tectonic disturbance zone, on rock barings with relative increases of the radioactive elements content) increases up to 15-20 mkR/h (130-175n Gy/h).


Technogenic pollution areas with anomaly high radioactive, where the gamma-radiation intensity reaches 600 mkR/h, but sometimes 5000 mkR/h are located mainly on oil fields territories in South- Western area of the peninsula and around iodine plants as well. On the map of pollutioned areas showed by the radioactive hazard sign. Baku is surrounded bythem, that is the pollution hazard of atmosphere by radioactive gas-radon.


The main cause of oil fields and territories pollution of the iodine plants is the technogenic process, connected with the developing and exploring of oil fields, iodine and bromine production, equipments repair, oil refining and so on and during above mentioned processes, the radionuclides of the natural origin with producted oil come out on the surface and pollute the environment.


This map may be used for research medical and radioecological organizations for radioactive studies conduct, recognizing the active tectonic disturbance and choosing the areas for building various constructions.
