Abstract

       The Uranium (238U), Thorium (232Th) and Potassium (40K) activity of specific in (Bq/kg) are measured (10) differentness types of milk which are available in market-place of Iraqi. Aspectrometry gamma ray of methodic with a NaI(Tl) detector its using for radiometric measurements. Also calculates the hazard of radiation indicates (radium equivalent activity and internally hazardous index tab) and effectiveness of Ingestion dose every sampler.


The activity of specifics in a sampler of milk was varied between from (0.274±0.158) Bq/kg to (7.851±0.877) Bq/kg, for 238U, For 232Th between from (0.821±0.273) Bq/kg in (3.067±0.569) Bq/kg and for 40K between (266.558±5.018) Bq/kg to (485.740±7.197) Bq/kg. In addition to, it is found that radium equivalent activity and internally hazard indexing to the sampler of milk ranged between (27.341) Bq/kg to (48.035) Bq/kg and from (0.07867) to (0.14720) respectively. So, the range summations ingestive effectiveness dose was variedly between (4.861×10-5) Sv/y to (1.541× 10-4) Sv/y. This search proves that the radioactivity of natural, hazard of radiation references and dose of effective ingestion was lower than the safekeeping, except some value of potassium.
