The aim of this research is to measure the concentrations of radon gas for nine kinds of imported fertilizers samples that are widely used due to what they can cause of an increment in natural radioactive level of soil, and that will affect the increase in the environmental contamination level with radiation. The results of the research show, the concentrations of radon gas C Rn ranges from 161.9-251.98 Bqm-3 with the average value 208.01±32.8 Bqm-3 , the surface exhalation rates for radon gas x ranges from 0.249-0.388 Bqm-2 h-1 with the average value 0.320±0.06Bqm-2 h-1 , the mass exhalation rates for radon gas E m ranges from 0.183-0.285 Bqkg-1 h-1 with the average value 0.235±0.04Bqkg-1 h-1 , the concentrations of radium gas C Ra ranges from 0.365-0.57 Bqkg-1 with the average value 0.47±0.07 Bqkg-1 and alpha index Iα ranges from 0.0018-0.0029 with the average value 0.0023±0.0004. From these results, the highest existence of a significant increase in the concentrations of radon gas in mono-ammonium phosphate Jordan 1 sample, but the lowest concentration of radon gas in ammonium phosphate Iran sample.
The impacts of gamma-beams and He-Ne laser of optical properties for CR-39 track indicator were studied. Twenty locations separated into five gatherings. In the first-place aggregate, one finder un-irradiated (control).
In the present study ten samples of bottled water from Baghdad conservative were taken to measure the concentration of radon gas by using nuclear track detector LR-115.The result obtained are varying from(0.033)to(0.007)pCi.l-1and these values are very low than the allowed limits (5) pCi.l-1, and specific activity from bottled water has been calculated which was vary from (0.00027)to(0.00126) Bq.l-1 and these values are very low than allowed limits (0.0123) Bq.l-1 that mean the bottled water was treated with good treatment to decrease the side effect of radon
The purpose of this study is to measure the concentration of uranium through 20 samples of human blood from healthy people and patients with leukemia, where the concentration of uranium increased by working in an unhealthy environment that led to people being exposed to cancer. The CN-85 was used to measure and determine alpha particles. Blood samples were dried and 0.5 g of each sample was obtained. The reagent was then bonded to a neutron stream using an (Am-Be) and 5 × 103 n.cm 2s-1 for seven consecutive days. The reagents were then scrapped with NaOH and 6.25 N for five hours. The intensity of the effect was measured by the optical microscope and compared with standard samples prepared in vitro. The increase in the proportion of uranium in the blood was caused by the military wars in 1991 and 2003 where the use of depleted uranium in the munitions and the war in abundance. The concentrations of uranium for healthy people ranged from (0.077 to 0.216 ppb), at a rate of (0.121 ppb). Patients ranged from (1,330-1.960 ppb) at a rate of (1.671 ppb). The acceptable value from ICRP is (0.810 ppb).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
