Gamaspektrometrijska kontrola hrane za ljude i životinje nakon akcidenta u Černobilju

Abstract

Nuklearni akcident u Černobilju koji se desio 26.04.1986.godine u bivšem SSSR-u, (danas Ukrajina) izazvao je veliku pažnju i zabrinutost javnosti zbog moguće kontaminacije životne sredine. Radioaktivni oblak je do naših prostora stigao za nekoliko dana, kada su u uzorcima aerosola i padavina u bivšoj Jugoslaviji detektovani radionuklidi poreklom iz Černobilja. Laboratorije u Srbiji koje su bile opremljene za merenja su započele ispitivanje radioaktivnosti odmah nakon akcidenta, a u Laboratoriji za Radijacionu higijenu Naučnog instituta za veterinarstvo Srbije sadržaj radionuklida se ispituje gamaspektrometrijski u namirnicama i hrani za životinje od 1989. godine. Godišnje je analizirano od 206 do 2400 uzoraka. Od toga je najviše bilo uzoraka ribljeg brašna, mesa, riba, mleka u prahu, itd., koji su većinom bili radijaciono-higijenski ispravni i bezbedni za upotrebu. Nakon akcidenta u Fukušimi 2011. godine pojačana je analiza hrane koja dolazi iz Azije. Najveći broj ispitanih uzoraka su bile ribe iz Tajlanda, Kine i Vijetnama, a ispitivani uzorci su bili radijaciono-higijenski ispravni i bezbedni za upotrebu.

The nuclear accident at Chernobyl, which occurred on 26 April 1986 in former SSSR, (now Ukraine), caused a great deal of attention and public concern about the possible contamination of the environment. In a few days the radioactive cloud came to our country, when radionuclides were detected in the samples of aerosol and precipitation. Laboratories in Serbia have begun testing radioactivity in food samples immediately after the accident, while radionuclide content is examined in food and feed in the Laboratory for Radiation Hygiene of the Institute of Veterinary Medicine of Serbia since 1989 by gamma spectrometry method. It was measured from 206 to 2400 samples annually. The most analysed samples were fishmeal, meet, fish, milk powder, etc. Almost all samples were radiation-hygienically correct and safe for use. Number of analysis of food that comes from Asia was increased after the accident in Fukushima in 2011. The largest number of samples have been fish from Thailand, China, Vietnam. All of the samples were radiation-hygienically correct and safe for use.
