Rate of radiation leakage from the CT-Scan rooms has measured for 10 public Hospitals in Iraqi Kurdistan, using radiation survey dosimeter. Annual exposure dose considered as a main factor to asses risks of that leakage on the health of operators and auditors. Average leakage dose measured at the control room, table of operators, the main doors, an...

The radionuclide concentrations in the drinking water from two categories of water resources, i.e., underground water (spring and well waters) and surface water from Erbil-governorate(Kurdistan region-Iraq), were estimated by using well calibrated NaI(Tl) gamma spectrometry. Drinking water samples were collected during the dry seasons, from July to...

In this study the assessment of indoor radon concentration in the air of Qaysare in Erbil city have been studied by using CR-39 Solid–State Nuclear Track Detector Technique. A total of 18 selected zones inside the suq have been selected to place the dosimeters. The average radon concentration was found to be 21.54 ± 8.017 Bq/m 3 which is fortunatel...

In order to assess effects of long term exposure of radon gas, CR-39NTDs exposed to indoor radon during summer season in the rest halls (ground floor) of 20 selected Kindergartens of the districts of Koya, Iraqi Kurdistan. Ventilation rate affect on the results of indoor radon concentration for each kindergarten. Good ventilation got a low level of...

The aim of the study was to compare radon concentrations and effective dose equivalent in state hospitals inside the Erbil city having different periods of building. Effective doses were estimated in different floors of the five selected hospitals by using the (CR-39) solid state nuclear track detectors with the guide of ICRP Publication 66. The ha...

Twenty-five water samples of springs were taken from different locations in the Erbil / Iraqi Kurdistan. The annual effective dosage of radon gas ingestion and inhalation was determined in spring water samples consumed by residents of Erbil city using the RAD7 detector. The highest radon activity concentration was reported in the Doli akoyan/gale f...

In this study, the analysis of radon activity concentration in 11 types of rock samples has been carried out using a radon monitoring system which consists of long-tube technique equipped with CR-39 SSNTDs as a passive method and electronic RAD7 solid-state detector as an active method. The rock samples were collected from different mountainous are...

Abstract In this study, we determined the activity concentrations of naturally occurring radioactive nuclides in plant crops and the corresponding soil collected from greenhouses and agricultural fields in Erbil city in the Iraqi Kurdistan Region by using a high purity germanium detector. The soil-to-plant crops transfer factors were determined fo...

The present study is to determine the activity concentration of radioactive nuclide in plant fertilizers used in agriculture in Iraqi Kurdistan region using high- purity germanium detector (HPGe) gamma spectrometer. The results showed that the range of activity concentrations for 226Ra, 232Th, 40K and 137Cs in chemicals and organic fertilizers are...
