Abstract:
To establish at which extent the micronuclei (MN) frequency is influenced by occupational exposure to ionizing radiation, peripheral blood samples collected from 2151 subjects of both genders, smokers and non-smokers were analyzed. Among them, 378 (17.6%) were unexposed while the other 1773 (82.4%) were exposed to ionizing radiation for periods between 1 year and more than 30 years, at levels never overpassing legally regulated limits. The final results showed that for all investigated categories, MN frequency monotonously increases with the age by 1.75 ± 0.17 times in the case of exposed subjects, but independent on gender and smoking habit.

Construction of Frequency Distribution
First, make a table with two columns—one with the title of the data that needs to be organized, and the other column for frequency. [Draw a third column for tally marks if needed]. Then, take a look at the items given in the data set and decide if an ungrouped frequency distribution table or a grouped frequency distribution table would be more suitable. If there are large sets of different values, then it is...
