The effective dose equivalent for potassume K40 in human body as cause as ingestions of tooth past

Abstract

In this research we used 12 tooth past samples which it more used from the local market, three of them specialized for babies with banana flavor, chocolate and melon , by using UCS-20 system computerize with scintillation detector sodium iodide activated with thallium NaI (Tl), to calculate it is content from radioactive potassium K40. The estimated value for the efficiency was 0.42% taking in account the geometry arrangement the maximum value of the activity of radiation potassium K40 was in sample A,16.83 Bq and the maximum value was 0.841Bq in sample G, the constriction of the radioactive potassium was in between 0.003mgm up to 0.067mgm. The equilibrium factor between the activity and the sample content of potassium in all samples was 0.0311Bq / mgm. The effective equivalent dose calculated taking in account the average daily intake and it is value was averaged between 0.073µSv/y and 1.606 µSv/y from all these results we can obvious that the effective equivalent dose values within the limit average annuli dose for radioactive potassium K40 as it decided from the national commotion of radiation protection.
