Background: Inspection of the level of radioactivity from radionuclides in soil is important for the assessment of the exposure to natural radiation. Materials and Methods: Ten samples from soil were collected from different sites of Kirkuk-IRAQ and the level of natural radioactivity was measured using gamma-ray spectrometry based on a high purity...

The natural radioactivity concentrations in 10 samples from different raw and construction materials in Kirkuk city of Iraq were measured using a hyper purity germanium (HPGe) detector. The determined average values of the specific activity were 38.68 Bq/kg (226 Ra), 11.84 Bq/kg (232 Th), and 169.98 Bq/kg (40 K). The results have been compared with...

This study deals with the process of finding concentrations of Uranium in human blood in central and northern Iraq (Erbil, Samarra and Baghdad) for worker in radiation field in X-ray, MRI, CTS units and from control group, and finding the relationship between uranium concentrations and the number of working years in the field Radiation and type of...

This Thesis for my student Omar Kareem Younus (M.Sc.)

The CN-85 nuclear track detector has been implemented for determining uranium concentration in human urine sample for different radiation workers in different Iraqi government, hospitals (nuclear medicine unit worker , X-ray and MST worker {the ministry of science and technology}), for different ages, gender and working years. The exposure method w...

The aim of this study is to find the uranium concentrations in urine samples for workers who are works in many factories in selected locations in Iraq, these are may be exposed to the radiation materials in their works, by depending on the number of working years. To achieve this aim, a new mathematical model is constructed through depending on the...

In this work, the outdoor radon concentration level and lung cancer risks have been measured in different Iraqi radiation locations during the summer season 2012 by using time integrated passive radon dosimeters containing LR-115 Type II plastic track detectors. These measurements were carried out in the locations for an exposure time of 60 day. Th...

The present paper aims to determine the radon concentration in a ten different imported samples of tea collected from Iraqi local markets. Solid state nuclear track detectors CN–85 was used to record the tracks of alpha particles released from radon content within the samples. A cylindrical chambers of U-shape containing the grained samples were us...

Inhalation of radon (222 Rn) and daughter products are a major source of natural radiation exposure. Measurement of indoor radon concentrations were performed in the two hundred rooms for the 25 apartments in Erbil city by using long term technique (CR-39 SSNTDs) for 90 days exposure time and short term technique (radon monitor) for 2 hours exposur...

The current study aims to build a mathematical model in order to assist the researchers to calculate the uranium concentrations in urine samples for labors in factories whom spend several years of work. So a new mathematical model is constructed by several parameters. The proposed mathematical model covers samples for labors who are working in many...

In our work, we have used mathematical modeling to determine the uranium concentrations in the urine samples of workers in radiation field according to the number of working years. The work aims at constructing a mathematical model to determine the uranium concentrations in the urine of the radiation workers based on the number of working years. Th...

The variation of the bulk etch rate (VB) of nuclear track detector CR-39 with the normality of the chemical etchant were studied. The removal thickness measurement method is used to determine the bulk etch rate. the detectors were etched by an aqueous solution of NaOH with normalities (4, 5, 6, 7) N at temperature (701) oC. It was found that the b...

In this work, the outdoor radon concentration level and lung cancer risks have been measured in selected locations in northern and central Iraq during the summer season 2012 by using time integrated passive radon dosimeters containing LR-115 Type II plastic track detectors. These measurements were carried out in the factories for an exposure time o...

This research describes the results that have been obtained from the alpha particles after carrying out the present study. The study was conducted on 30 urine samples taken from women, who were either infertile, had weak fertility or had uterus tumor. The age of those women ranged between (21-43) years. The results showed that the low level of alph...

There are many changes that have affected badly the environment and people’s life in Iraq during the last two decades as a result of wars and suspected used of prohibited weapons and what ways these reveal dangerous diseases. The objectives of the present work was to measure the uranium concentration in urine taken from workers in factories and hos...

Radon activities and radon exhalation rate have been measured from building materials (gravel, cement, sand, gypsum, gypsum board, ceramic tile and block ) on the public hospitals in Iraqi Kurdistan Region using passive (CR-39NTDs). The highest radon concentration was found in sand samples ( 480.71 ± 4.52 Bq/m3) and lowest was found in ceramic tile...
