background: uranium poses both chemical and radiological hazard to the living system. drinking water from river is one of the major sources of uranium intake. dissolution of minerals, washout from rain water, rock-water interaction, agricultural run off, and industrial disposals are some of the sources of uranium in river water system. present study was aimed to determine the uranium in the wat...

background: natural radionuclides are always present in the environment. human exposure to the background radiation is inevitable. it is therefore important to assess health risk associated with these radionuclides. materials and methods: the distribution of natural radionuclides 238u, 232th and 40k in soil samples collected from all the twenty (20) local governments headquarter areas in ogun s...

OBJECTIVE Gonadotropin-secreting pituitary adenomas carry a high risk of local recurrence or progression (R/P) of remnant tumor after first surgery. The clinical characteristics and the long-term outcome of these silent adenomas, which show no signs of endocrine hyperfunction, differ from those of other types of pituitary adenomas. However, to date, no study has focused specifically on gonadotr...

OBJECTIVE To determine the clinical, biochemical and radiological prognostic indicators and to compare the performance of six staging systems in patients of hepatocellular carcinoma (HCC). STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Department of Gastroenterology, Doctors Hospital, Lahore, from October 2007 to December 2013. METHODOLOGY Patients with HCC were included. Bas...

conclusions portable radiological examinations did not expose healthcare providers to high doses of ionizing radiation. nurses’ radiation protection knowledge was limited and hence, they require in-service education programs. results the mean of participants’ radiation protection knowledge was 4.77 ± 1.38. the most prevalent radiation protection behavior of nurses was leaving the intensive care...

Background: Man-made  radionuclides, which are present in environment, have been created by human activities and added to the inventory of natural radionuclides for example 3H, 131I, 129I, 137Cs, 90Sr and 239Pu, in spite of the amount added is little compared to natural quantities. The aim of this study is to estimate the levels of radiological doses in the soil samples collected from different...
