Abstract
We have been measuring the radon concentrations, the exhalation rate (surface and mass), effective dose and radium content, the level allowed in soil and water samples collected from the Graduates villages zone in Abu Matamir center Nubaria sector West Nile Delta, Egypt. The study area is located at the line showing latitude (30o 40’ and 30o 50’) North, and longitude (30o 05’ and 30o 25’) East, where this part is an important area and that of the most prominent features is considered the proliferation of cultivated land and the diversity of soil as well as water resources, which make them produce a variety of agricultural crops. Surround by the study area from the north to the west of Alexandria Governorate and from the north-eastern Damanhur city and Middle Western province and the south-east EL Menoufia Governorate to the south Sadat city, as the study area surrounded El Nubaria canal and El-Raiah El-Nasery and many Linings (irrigation canals) and drains as well as they are located in the eastern part of the Egypt-Alexandria road. The experimental technique used in the measurement of radon concentrations was passive technique. Solid state nuclear track detectors SSNTDs (CR-39 & LR-115) detectors used to detect about radon concentrations. The soil samples were dried in an oven at 110°C for 2 hours, minced, sieved by 1 mm mesh, weighted and put it in a cylindrical container (16 cm height & 9.4 cm diameter). The container contains two detector pieces (CR-39 & LR-115) 1.5 cm x 1.5 cm sticks tightly in the bottom of the container-cover. The results we have obtained could be explained as follows : Both of detectors showed that the highest concentration of radon average value was 692.81 ± 29.88 Bqm-3 in the Taha Hussein village and 652.67 ± 26.78 Bqm-3 in the 19 Luhoom village, where the radiation levels in both villages above the level set by were EAP and UNSCEAR recommendations, where it was between 200 - 600 Bqm-3, the lowest concentration of radon was in the Jeneklees villages of the airport boundaries where radon concentration was 222.88 ± 17.26 Bqm-3 is which considered within the allowed universally recommendation. Comparing the results of the water samples collected from groundwater and surface water, we can say that the groundwater, wells in particular showed that: 1-There was generally a positive correlation between radon concentration and the total dissolved salinity in the groundwater samples, may be contain at a uranium element in components. 2-There was no relationship between radon concentration and total dissolved salinity in surface water because it is not pure water such as drain, public water and irrigation canal that feeds these areas because evaporation processes and it is prone to throw waste and drain containing various elements. 3-There was no relationship between radon concentration and pH for all water samples. 4-The radon concentration in deep wells was higher in shallow because the greater the depth increased closer to the ground, which may be a container material enters uranium in components.
