Study Population

Case control study that will include 100 participants (50 radiation exposed workers will be compared with 50 healthy age and sex-matched control group not exposed to radiation.

G power program was used to calculate the sample size for two independent groups. power calculation estimated to detect an effect size of 0.88 of difference between means of two independent groups, with a p value < 0.05 and 80% power,.

Description

Inclusion Criteria:

  • • The radiation exposed workers will include nurses, technicians and physicians.

These persons will be occupationally exposed to different radiation sources.

Exclusion Criteria:

  • History of diagnostic X-rays, radiotherapy and/or chemotherapy 12 months prior to sampling.
