Resumo
Natural and artificial radionuclides in feedstuffs with concentration levels
surpassing the brazilian (CNEN-NN 3.05, January 2005) and international
(IAEA 115 Safety Series, 1996 and Codex Alimentarius, 2006) limits are
harmless to the human health and an effective control is needed in order to
only allow consumption of products presenting radiation levels below limits.
Since 1988, after the Chernobyl accident, the Environmental Radiometric
Laboratory at the Nuclear and Energy Research Institute, IPEN-CNEN/SP
(Instituto de Pesquisas Energéticas e Nucleares), performs, on a regular
basis, analysis of potassium-40, cesium-134 and cesium-137 concentrations
in feedstuffs and food commodities imported and exported by Brazil.
The present work covers mostly a decade of results, from 1996 to 2007,
assessed from the measurements of almost 2600 samples. The imported
products were from several foreign countries like South Africa, Polland and
Belgium and the exported ones are originated from 14 Brazilian States and
111 regions.
Nearly 90 different kinds of feedstuffs and food commodities were
measured, including condensed milk, milk powder, soy beans, sugar, raw
coffee beans, etc. All samples were analyzed by high resolution gammaspectrometry and the results, compared with brazilian and international
limits, released as a technical report.
The radioactivity present in all analyzed products was within the
international limits, allowing to conclude that consumption of such goods
offers no health risk derived from radiation. Potential relationships between
the type and the origin of the products exported and imported by Brazil and
the radionuclides concentrations are also approached.
Finally, all results will contribute to the establishment of a radiometric
database for the radionuclides concentrations in the feedstuffs and food
commodities produced in Brazil.
