In this research the activity of radon gas in air in Baghad governorate,Iraq, using “alpha-emitters track registration (CR-39) track detector were measured. This measurement was done for selected areas from Baghdad Governorate, The results obtained shows that the highest average concentrations for Rn-222 is (179.077 Bq/m^3) which was recorded within Al-Shaaib city and less average concentrations was (15.79 Bq/m^3) in the nearby residential area of Baghdad International Airport and the overall average concentrations is (86.508 Bq/m^3) for these regions. Then the radon concentration was measured annual effective dose calculated from radon concentration and found in range from 0.4031 mSv/y to 4.5179 mSv /y with an average value of 2.1824 mSv/y. The annual effective dose of radon was within the allowed international limits.

Different Origins

The nuclear track detector CR-39 is used in the detection of radon gas concentration in selected samples of cosmetics in the local market. Products of wide use are selected and employed in the current study. Six types of cosmetic products of different origins are tested by taking equivalent quantities of these products and putting them in plastic boxes. The detector is left with the samples for a period of 50 days. In addition to measuring the rate of surface evaporation of radon gas, measurements of the annual equivalent dose of radon gas are also carried out. The results show that the highest concentration of radon gas is in Charcoal Facial SCRuB (American origin) and it is equal to 0.0795 Bq/m3, whereas the lowest one in "bb" cream basis (5 in 1) is equal to 0.0355 Bq/m3. Based on specific international organizations and agencies, the concentration of radon in the samples under consideration is within the acceptable limits.

In this work, we have study the concentration of radon gas in seven cement samples from different regions in Iraq (Kofa, Sulaymaniya, Kubesa, Karbala, Al-Kaem, Basra, and Almas cement) by using alpha-emitters registrations that emitted from radon gas in CR-39 nuclear track detector. Sealed-cup technique that used in this study to determine the alpha emitters from radon gas. The results obtained shown that the highest average radon gas concentration in cement samples which was (55.16 Bq/m3) for Almas samples, while the lowest average radon gas concentration in cement samples which was (24.13 Bq/m3) for Karbala samples. The current results show that the radon gas concentration in all cement samples that studied is below the allowed limit from International Commission of Radiation Protection (ICRP) agency.

Henna leaves are a priority material for hair dyes and body tattoos and have been used for this purpose for decades. In Iraq, henna is used widely but it requires substantial controls. Iraq is considered an environmentally polluted area as a result of the wars it has experienced, hence, this study has been conducted to calculate the level of 222Rn contamination in henna leaves using a CR-39 nuclear track detector. The leaves were collected from the province of Basrah, which is located in southern Iraq and is famous for cultivation of this plant. The radon concentrations were found to range from 12.140 to 16.255 Bqm?3 in Al-Faw, and from 7.613 to 11.111 Bqm?3 in Abu Al Khasib. Radon activity ranged from 6.09?10?4 to 8.16?10?4 Bq Radon specific activity ranged from 1.22?10?4 to 1.63?10?4 Bqg?1 in Al-Faw, and from 7.64?10?5 to 1.12?10?4 Bqg?1 in Abu Al Khasib. The radon exhalation rate ranged from 4.05?10?4 to 5.43?10?4 with an average of 4.69?10?4 Bqm?2d?1 in Al-Faw, and from 2.54 10?4 to 3.71?10?4 with an average of 3.22 10?4 Bqm ?2d?1 in Abu Al Khasib. After obtaining the results, one can conclude that the henna plant collected from these areas is safe for human use and is free from high rates of 222Rn.

The health hazards of the radioactive gas radon on general public are well known. In order to understand the level and distribution of 222Rn concentrations in soil-gas in Babil province, we have measured the radon gas concentration in soil samples of different areas in Babylon (Al-werdeiaa, Al-seiahy, Al-Thewrae, Al-muhendisen, Al-keliss, Nadeer) by using alpha-emitters registrations which are emitted from radon gas in nuclear track detector (CR-39). The obtained results have shown that the highest average radon gas concentration in soil sample was found in Al-muhendisen and Al-werdeiaa samples, which was (32.75 Bq/m3), while the lowest average radon gas concentration in soil samples was found in Nadeer sample, which was (25.85 Bq/m3). The present results show that the radon gas concentration in all soil samples is below the allowed limit from (International Commission of Radiation Protection) (ICRP) agency.
