Radon Concentrations

In this study, concentrations of radon were measured for seventeen samples of soil distributed in three Sulphuric Spring, in addition to other regions as a background in Hit City in AL-Anbar Governorate. The radon concentrations in soil samples measured by using alpha-emitters registration that emits from radon (222Rn) in (CR-39) track detector. The concentrations values were calculated by a comparison with standard samples. The results show that the radon concentrations in first spring varies from (258.253- 347.762 Bq/m3), second spring (230.374-305.209 Bq/m3), third spring (292.002-336.023 Bq/m3) and the average radon concentration in other regions (187.821 Bq/m3). As a conclusion of the study radon concentration in Sulphuric Spring is relatively higher than the background.

Radon Concentrations

Measurements of radon concentration, effective radium content, potential alpha energyconcentration (PAEC) and annual effective dose (AED) were estimated for soil samples in fifteen locationsof the Baghdad governorate (Karakh) in the central part of Iraq. In this survey we used the can technique,containing nuclear track detector (CR-39). The obtained values of radon concentration measurements weregenerally low, ranging from 38.12±13.46 to 94.51±16.5 Bq/m3, with an average 66.07 Bq/m3, while theeffective radium content varied from 5.80±0.21 Bq/kg to 14.39±0.33 Bq/kg with an average 10.09 Bq/kg. The average of the PAEC and AED were assessed to be 7.14 mWL 1.66 mSv/y, respectively. The resultsof the present study shows that the radium content are lower than the allowed limit reported by Organizationfor Economic Cooperation and Development (OECD) that is equal to 370 Bq/kg. In general, it is seen thatthe AED limit was within the recommended reference level (3 mSv/y to 10 mSv/y) of the World HealthOrganization. Also, it is found that there is a strong correlation (R2= 1) between radon concentrations andeffective radium content. The results obtained from this study indicate that the locations of Karakh hasbackground radioactivity(radon concentrations) levels within the natural limits.

CR-39 nuclear track detector is utilized to measure the uranium content and radon 222Rn concentrations in soil samples. Uranium concentrations in soil samples varied from 0.008 to 0.05 ppm with mean value 0.025±0.013. Radon concentrations is founded between 31 and 92 Bq/m3 with mean value 56.72 and standard division, SD, 17.29. Radon Excess Lung Cancer per Million Persons per Year is determined with mean value 863 and standard division, SD, 261.65 (463.81-12082.8). Also, Annual effective dose, E (msv y-1), has a range from 0.77 to 2.32 with mean 1.44 and SD 0.44.

Measurements of radon gas concentrations were carried out for 12 soil samples at 3 sampling depths (surface, 5 cm and 10 cm) collected from (4) locations in south Baghdad suburbs (Bu'aitha) using solid state nuclear track detector CR-39 and sealed can technique. Radon concentrations for surface samples were ranged from 402.2 to 1538.4 Bq.m-3 with an average 994.4 Bq.m-3. Whereas, radon concentration was ranged from 813.1to 2050.4 Bq.m-3 and from 1309.8 to 4626. 1Bq.m-3 with an average values of 1359.8 Bq.m-3 and 2338.3 Bq.m-3 for 5 cm and 10 cm depths respectively. Maximum radon level was found at the location near to the river (site S4) while the minimum radon level was found at residential area (site S2). Radium contents were ranged from 0.42 to 1.62 Bq.kg-1, from 0.85 to 2.15 Bq.kg-1 and from 1.38 to 4.86 Bq.kg-1 with average values of 1.04, 1.43 and 2.46 Bq.kg-1 for surface, 5 cm and 10 cm depths respectively.

Environmental Activity

Radon, thoron and their progenies in the indoor environment are considered as one of the health hazards. The alpha emitting nature of these gases made it possible to detect in indoor environment with the help of nuclear track detector techniques. The soil is the main source of indoor radon as it contains varying amounts of uranium and thorium. Thus the exhalation of radon from soil and its environmental activity needs to be studied. In the present study, the measurement of the indoor radon-thoron from the indoor environment and exhalation from soil are carried out using solid state nuclear track detector technique from Sirsa and Bhiwani districts of northern part of India. The canister technique was used to measure the radon ex- halation rate from the soil samples collected from the study area and pinhole based radon-thoron dosimeters were used to measure indoor radon and thoron concentration. The results show that indoor radon concentration varied from 9 to 28 Bq/m3, with an average of 18.9 Bq/m3 and from 5 to 21 Bq/m3, with an average of 13.8 Bq/m3, for Bhiwani and Sirsa, respectively. Similarly, thoron concentration varied from 14 to 48 Bq/m3, with average of 28.9 Bq/m3 and 27 to 54 Bq/m3, with the average of 39.0 Bq/m3, for Bhiwani and Sirsa, respectively. The mass exhalation rates from soil samples were also measured, to estimate their contribution to indoor radon. A correlation study was carried out between soil exhalation rates and indoor radon concentration.

Soil Gas Radon

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.
