The aim of this study is to calculate the alpha rates emitted from some parts of animal which are not consumed (bones samples) and re-enter the human food chain as bone meal in various fodder products, or as fertilizers. This is performed by count the alpha tracks emitted from the natural radioactive nuclei (pb-210, po-210, Ra-226) of three common animals bones (beef, sheep, and chicken) by exposed the CN-85 detector to some grams of the samples filled in clear plastic cup (cup technique). The detectors were exposed to the samples for 60 days and then etched by water bath with 2.5N (NaOH) solution at 60°C. The results showed that the mean alpha emission rates of the samples were 50.85 Bq.m-2, 58.24Bq.m-2, and 67.99 Bq.m-2 for sheep, beef and chicken respectively. The highest alpha emission rate observed in chicken samples and the lowest rate of alpha emitters observed in sheep samples, and the optimum etching time of CN-85 when its used to detect the natural alpha particles is 40 mints.
