“…The results of the specific activity of 238 U, 232 Th, and 40 K in Table (2 The results of total of AED in unit mSv/y due to 238 U, 232 Th, and 40 K in all samples of the present study were lower than global limits according to ICRP reported which it is equal 1 mSv/y [16] as shown in Table (3) and Figure (5). Also, the results of cancer risk in all date samples in the present study were within the permissible limit (2.5×10 -3 ) [10,17], As well as, the results of Raeq and H in were less than 370 Bq/kg [18] and 1 [19], respectively that is safety stage.…”

The aim of the present study is to assess some radiological hazard risk parameters such as the annual effective dose (AED), Fatal Cancer Risk (FCR), Hereditary Cancer Risk (HCR), radium equivalent (Raeq), and Internal hazard index (Hin) due to specific activity of 238U, 232Th, and 40K in some samples of date in Al-Qasim subdistrict, Babylon governorate. The specific activity was measured using gamma-ray spectroscopy with NaI(Tl) doctor. The average values of the specific activity in unit Bq/kg for 238U, 232Th, and 40K were 10.83 ±1.22, 4.94 ±0.80, and 341.36 ±15.25, respectively. While, the average values of total AED, FCR×10-3, HCR×10-3, Raeq, and Hin were 0.210±0.018 mSv/y, 0.737±0.064, 0.198±0.008, 44.18±3.10 Bq/kg, and 0.148±0.011, respectively. The results show that, all values of 238U, 232Th, and 40K were lower than the global limit according to UNSCEAR 2008 (33 Bq/kg, 45 Bq/kg, and 420 Bq/kg), except two samples have 40K higher than global limit. these because increasing used chemical fertilizers by peasants. Also, it is found that all values of the radiological hazard risk parameters in the present study were lower than global limit according to UNSCEAR, ICRP, OECD, etc. So, it was concluded that the date samples in the present study does not cause any danger to the human health when its consumption.

“…After collection of samples, it is packed in a plastic bag, labeled with their sample codes, and then transferred to nuclear laboratory at university of Kufa. Next, there are many steps to preparation of samples which it is cleaned, dried at temperature 40oC for 5 hours, crushed by electronically mill, sieved by sieve (pore-size 0.8 mm), weighted by electronically balance, mobilized in the plastic container, and finally, stored at least for four weeks to examine secular equilibrium between 226Ra and 222Rn [11].…”

In this study, measurement of alpha emitters such as radon-222, radium-226, and uranium-238 levels in Iraqi of medical plants samples using CR-39 detector. As well as, annual average internal dose (AAIED) and risk of an excess cancer fatality per million persons (RECFPMP) due to ingestion of radon, radium, and uranium from samples in the present study were calculated. The average values with stander error of radon-222, radium-226, and uranium-238 activity in unit Bq/kg were 5.22 ±0.94, 0.3409 ±0.061, and 5.20 ±0.942, respectively. While, the average values of AAIED and RECFPMP due to alpha emitters in all samples of medical plants were 0.348±0.063 μSv/y and 1.21±0.221, respectively. Analysis of samples has been studied and therefore compared with the internationally published and permissible range that has been recommended by the international scientific committees. Accordingly, it was found that radiation levels in medicinal herbs available in local markets were fallen within natural and allowed limits and therefore don't impose any danger out of the radioactive aspect in terms of human consumption and use of medical treatment.
