Abstract |
|
|
| Organic and inorganic feeds that enhance faster growth in chicken are on high demand by suppliers of chicken meat in and around Kampala. Competition in chicken business, however, raises concerns on the quality of chicken feeds and meat, as well as risk of cancer and other biological effects of radiation to consumers of chicken products. This study focused on determining the specific activity concentrations of 226Ra, 232Th and 40K in chicken feeds, meat and bones supplied in Kampala. Equal broiler and kroiler samples of feeds, meat and bones were collected and analyzed using γ-spectrometry method. Kroiler samples show higher activity concentrations than broiler samples. All samples have safe activity concentration levels of 226Ra. Only broiler feeds have activity concentrations of 232Th below the world limit, and both broiler and kroiler meat have activity concentrations of 40K above the world limit of 400 Bq kg−1. The heightened activity concentration levels of 232Th and 40K require regular radionuclide check-ups in chicken feeds and products. Radiological risk parameters need to be determined in order to check the health risks to consumers of chicken products in Kampala. |
