Measure the rate of Radiation Activity in Soil sample from the depth of Sindbad land in Basrah Governorate

Abstract

Uranium, radionuclide’s, thorium and potassium are relatively abundant in soils. Because of their radiation, these radionuclide’s pose exposure risks that can lead to health problems such as cancer for exposed people. There is therefore growing concern about the health risks associated with exposure to the natural sources of radiation in our environment. The specific activity 238U, 232Th, 40K,226Ra in forty soil samples collected from different locations of Al-sindbad land in the province of Basra – Iraq using Sodium Iodide NaI(TL) detector. The specific activities for the whole study areas were compared the Local, world average and permissible recommended limits. The results showed thatthe specific activity of226Ra,232Th,238U, and 40K, in the samples rang from( 17.14-39.07)Bq/kg, ( 1.8-22.88) Bq/kg, (0.68-2.24) Bq/kg and (278.11-402.29)respectively, Also evaluation of radiological hazard effects for Gamma ray (the radium equivalent rate (Raeq) which calculated from concentration of 232Th,238Uand 40K ranges between (30.72-65.48) Bq/kg with mean value of (43.362)Bq/kg, the absorbed dose Rate (D γ ) for the soil samples in the study area range from (26.54-43.92) nGy/h with an average value of(33.216)nGy/h, the annual effective dose rate (AEDEoo) range (0.13-0.22)mSv/y with an average value of(0.163) mSv/y, The annual effective dose rate (AEDEin) range (0.03-0.05) mSv/y with an average value of(0.04) mSv/y, The internal hazard index (Hin) range (0.2-0.35) with an average value of(0.255)and the external hazard index (Hex) range (0.15-0.25) with an average value of (0.186).The results of the present study have shown that the rates of Specific activity of226Ra,238U, 232Th and 40K, and radiological hazard effects Rate for Gamma-ray in environmental samples were all lower than the value of the global limit(33, 35, 30, 400)Bq/kg respectively according to UNSCEAR. We conclude from this study that the environment of Al-Sindbad land in the province of Basra – Iraq is within a normal background radiation.

Determination of Natural Radioactivity Levels and Radiation Hazards from the Soil of Tin Mining in Kyerwa District, Tanzania

“…The radioactivity level index (Iγ) is an additional radiological factor that can be calculated. The radioactivity level index (Iγ) given in Table 5 is used to estimate the rate of γ-radiation hazards linked with natural radionuclide in investigated samples [15,16]. The Iγ is defined by Equation 7.…”

“…Gonads, active bone marrow, and bone surface cells are regarded as the organs of interest by [12]. Hence, Equation ( 8) was used to estimate the Annual Gonadal Equivalent Dose (AGED mSv y-1) for the miners and the public around the mining areas due to the specific activity of 226Ra, 232Th, and 40K given in Table 6 [16,17].…”

Уран Кенін Өндіретін Аймақтарда “Топырақ-Өсімдік” Тізбегіндегі Радионуклидтердің Миграциясына Баға Беру (Әдеби Шолу)

“…Бұл жүргізілген зерттеулердің басым бөлігі қоршаған орта объектісі ретінде топырақ сынамаларын зерттеуге бағытталған.Қоршаған орта объектілерінің радиоактивтілігі негізінен 238 U, 232 Th, 226 Ra, 137 Cs және тағы басқа радионуклидтерімен, олардың ыдырау өнімдерінің мөлшері бағаланады [1][2]. Топырақтың осы орайдағы ерекшелігі-ол радиоактивті материалдардың соңғы бағыты және оның ұзақ мерзімді рөлі радионуклидтерді жинақтау және сонымен бірге ауаның, судың, өсімдіктердің ластануында осы заттардың негізі көзі ретінде әсер етеді [3].…”

Measurement and Analysis of the Distribution of Pb-214 Lead Isotope in Baghdad Soil using Remote Sensing Techniques

“…Therefore, there is a growing concern about the health risks associated with exposure to these sources of radiation in our environment. Several studies have been conducted on radiation health risk assessment in order to gain access to a reliable database on radiation health problems [3][4][5][6][7][8][9]. It is important to measure radiation parameters that affect the Iraqi population because high exposure to radiation may cause very large health complications such as carcinogenesis [10].…”
