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.

In this study the assessment radon concentration in sludge of OilFields in North Oil Company (N.O.C.) of Iraq have been studiedusing CR-39 solid–state nuclear track detector technique. A total of34 samples selected from 12 oil stations in the company have beenplaced in the dosimeters. The average radon concentration was foundto be 162.29 Bq/m3 which is fortunately lower than the standardinternational limit. The potential alpha energy concentration andannual effective dose have been calculated. A proportionalrelationship between the annual effective dose and radonconcentration within the studied region has been certified.

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.

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.
