conclusions the effective annual dose of interventionists who work in center 1 and 2 was 143.08 and 1226.78 msv respectively. the high radiation dose which delivers to the leg of physicians in center 2 can be an important cause of radiation dermatitis occurred on the leg of our interventionist. patient dose during most of the procedures was less than the threshold dose for occurring erythema bu...

ntroduction: The purpose of this study was to measure the radioactivity in the agricultural soil of south-east of Shazand Refinery Complex to determine both reliable baseline data on the radiation level and the radiation dose exposure to the farmers and inhabitants of the studied area. Material and Methods: This study was conducted on 21 soil...

Coals mined in some regions of the Transdanubian Middle Mountains in Hungary have elevated concentrations of Ra. The slags and ashes derived from these coals have been used as building material for schools and kindergartens. As the Ra reached up in these waste products of coal-firing systems, the gamma dose contribution in the buildings, which contained them, was calculated. In these places the...

Technical data on local CT practice in Western Australia were collected for five major CT providers using a self-completed questionnaire. The CTDIvol DLP and effective dose for each protocol were obtained and providers were ranked according to radiation burden for each clinical scenario. The mean, median, 75th percentile and standard deviation were calculated for both effective dose and DLP for...

Background: Human activities such as mining enhance the radioactivity levels above normal background which can lead to an incremental increase in the radiation risk to the population. Materials and Methods: 20 tailing enriched soil samples collected around Maiganga coal mine, Gombe, Northeast Nigeria were assessed for their 226Ra, 232Th and 40K contents using HPGe gamma-ray detector. Results: T...

In the present study annual exposure and inhalation dose due to radon and its progeny were measured in some selected dwellings of Hardoi District (U.P.) by using solid state nuclear track detector (LR 115 Type-II Plastic track detector). The measurement was repeated on a time integrated four quarterly cycles to cover all the four seasons (summer, rainy, autumn & winter) of the calendar year. Th...

introduction natural and artificial radionuclides are the main sources of human radiation exposure. these radionuclides, which are present in the environment, can be dissolved into water. evidence suggests that radionuclides being entered the human body through drinking or hot spring water can be harmful for human health. materials and methods in this study,10 samples were collected from ground...

Few cases of hydatid disease have been reported in India. The general impression is that the disease is rare. It is only occasionally that cases appear in the hospitals in large towns, and even these very often are not clearly brought out in hospital reports. The provincial annual reports in India show no separate heading for hydatid disease, and in hospital reports they are included under tumo...

The screening method, which employs readily available data, is an inexpensive and quick means of estimating vaccine effectiveness (VE). We compared estimates of effectiveness of heptavalent pneumococcal conjugate vaccine (PCV7) against invasive pneumococcal disease (IPD) using the screening and case-control methods. Cases were children aged 19-35 months with pneumococcus isolated from normally ...

In association with its nation building projects, the imperial government in Brazil under monarchic rule took some concrete actions based on proposals for physical education. The aim of this article is to investigate the meanings and significations attributed to this subject in the legislation and the annual reports issued by the Ministry of Business of the Empire (1831-1889), giving special at...
