EVALUATION OF EXCESSIVE LIFETIME CANCER RISK AND ANNUAL GONADAL EQUIVALENT DOSE DUE TO NATURAL RADIOACTIVITY IN VERMICELLISHATHA F. ALHOUS, ZAHRA MOUSA HAMZA, SHAYMAA AWAD KADHIM AND NAEEMA HADI ALI
Vermicelli is one of the common foods made from grains and it is a type of pasta and is characterized by ease of preparation. In the current study, the concentrations of 226Ra, 235U, 232Th and 40K Bq/kg was estimated in fourteen different types of vermicelli samples selected from markets in Iraq. Sodium Iodide NaI (Tl) detector was used to measure the concentration of these radionuclides. The concentrations of 226Ra, 235U, 232Th and 40K Bq.kg-1 were estimated to be 1.119, 0.051, 0.386 and 8.524. On the other hand, the average value of Raeq was 2.328 Â± 0.184 Bq.kg-1. Radiation hazard index of RLI, IÃ¡, IC, AUI, Hex and Hin have been calculated, and depends on the permission limits recommended by UNSCER is lower than the unity. Radiation doses DR, HE, AEDEin, AEDEout, AGED and AID, all these values were universally accepted. The risk of cancer ELCR were also estimated to be lower than the values allowed worldly. All data were statistically treated to find the correlation between them and calculate the p-value for all variables, the Pearson factor for comparison between most of the radiation parameters was of a strong positive and statistically significant relationship except (226Ra with 232Th and 40K) was weak and statistically insignificant. All results were less than the permissible limits assessed by UNSCER.
