Radiating safety

The sources of ionizing radiation in Azerbaijan belong to various scientific-research organizations (mainly to Sector of radiation researches of Academy of Sciences of Azerbaijan), medical objects and military divisions. In the Sector of radiation isotope sources Co-60, Cs-137 with activity about mkCuri are available for researches since 60's. Electron Accelerators ELU-4, ELIT-1, E-12 with electron energy up to 5KW and power of beam up to 1 KW also available. In various medical organizations (Institute of oncology, hospitals) are available isotope sources and X-ray equipment for radiotherapy and radiodiagnostics. After certain time of use the activity of isotope sources are reduced and cannot be used on target purpose. In these cases arises problems storage of radioactive wastes. The maintenance of radiating safety is connected with using and storage of these sources, and also with the problem of natural radioactivity of the country.
Practically all sources of artificial radioactivity (isotope sources, x-ray apparatus, the accelerators electrons) supplied with reliable protective and automatically blocking system and supervised by sanitary bodies. Negative influence on the radioecological conditions can finishing of potential opportunities special combinat "Isotope". Yet in 1994 assignments are allocated and work on reconstruction and expansion of "Isotope" are begun. A total cost of work makes 4 mln US dollars.
Since 1997 carrying out inventory of sources of ionizing radiation in the country. Sources of ionizing radiation was found out in Soyug-Bulag Akstafa region and Nakhchivan on the territories of military object, left by Russian militarists
One of major factors, complicating a radioecological conditions, is production, transportation and processing of petroleum. Petroleum extract on the surface of water contain radium, thorium, isotope of calcium which penetrate into ground, accumulate on walls of pipes, concentrate on local sites. In these sites a level of radioactive field exceeds permissible background level in 50-150 times.

For example measurements of Zolotovitskoy and Aliyev shows, that in separate sites of petroleum deposits Gum adasi the level of a radiating background reaches 600 mcR/h. Measurement of the radiating level in objects of oil pipelines (pump stations, reservoir parks, pipelines and etc) show, that the significant increase of a radiating background in an environment is not observed. It does not exclude an opportunity presence of the raised radiating level in objects themselves.
An abnormal high concentration of radionucleids fixed also in industrial wastes of chemical and iodium - bromide manufactures. In Baku on 1998 31 sites, mainly in central part of city, is established 157 sites local and area pollution by radionucleids with the level of radiation up to120-3000 mcR/hour.
On the territory of Azerbaijan exists very favorable conditions from a point - of view of a level of natural radioactivity. So, level of natural radioactivity within the limits of permissible norm and does not exceed 10-15mkr/hour.
