a study on natural radioactivity in virgin and agricultural soil samples collected from sungai petani was conducted using high-purity germanium. the mean activity concentrations of 226ra, 232th, and 40k in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 bq kg−1, respectively. the co...

the activity concentration of gross alpha and gross beta particles in four samples of borehole drinking water consumed in ibrahim badamasi babangida university (ibbu), lapai, niger state-nigeria was measured, using a portable single channel gas free proportional counter (mpc2000b-dp) detector. this study focused on cancer related problems and the bio-data of the environment was discussed as wel...

Since the publication of ICRP60, there has been a considerable amount of work carried out by many to reduce the dose received by patients during common fluoroscopy procedures. This has included equipment improvements, optimisation of equipment, use of fast film/screen combinations, etc. Papers have been published showing large dose savings can be made by attention to equipment (1, 2), but also ...

BACKGROUND An increased admission of high-risk patients to diagnostic and interventional radiological procedures with contrast medium has resulted in an increase of contrast-induced nephropathy, which now represents the third main cause of hospital-acquired acute renal failure. The pathogenic mechanism of contrast-induced nephropathy (CN) is unclear, but there is much evidence which indicated a...

Radiological examination is indispensable in current dental practice. Lately, dentists have become not only the beneficiaries of radiographic investigations required for diagnosis, but also their authors, as many dental offices have been authorized to have X-ray machines and carry out radiological activity. This is why dentists who perform dental X-rays have the legal and moral obligation to po...

conclusions our results in terms of asami scores are comparable with the published literature. furthermore, our return to work is better than most european studies (63%). all our patients said they would have the procedure again. we attribute this success partly to the multidisciplinary approach. we recommend early referral to a dedicated unit if there is any evidence of a non-::union::. result...

background: in response to the need for diagnosis and treatment, medical radiation has been increasingly used worldwide. this study investigated the medical utilization of radiation-related diseases among radiological technologists (rts) and factors that influence such diseases. materials and methods: data were collected from the taiwan national health insurance research database. a panel study...

Chest radiography is the most frequently used radiological chest imaging technique and also one of the most challenging. The technical aspects of this imaging modality are studied extensively. New approaches to image acquisition and display have been introduced in the past decade. As a general rule, establishing the presence of a lung disease process on the radiograph should constitute the firs...

The aim of the present study was to obtain data on the reliability and reproducibility of two non-destructive dental-age estimation methods in adults by calculating inter- and intra-observer effects. Both a morphological and a radiological technique available in the scientific literature were evaluated on a number of recently extracted teeth: the morphological technique was evaluated on a total...
