The radiation burden of radiological investigations

The radiation burden of radiological investigations.

The harmful effects of ionising radiation are widely acknowledged. It has been reported that young children, particularly girls, have a higher sensitivity to radiation than adults. However, the exact detrimental effects of radiation, particularly at the low doses used in routine diagnostic radiography, are unknown and the subject of much controversy. Computed tomography (CT) accounts for about ...

Knowledge of radiation exposure in common radiological investigations: a comparison between radiologists and non-radiologists.

BACKGROUND Radiological examinations are commonly requested for patients to aid clinical diagnosis. However, many doctors do not realise how much radiation dosage their patients are exposed to during radiological investigations. This study aims to assess and compare the knowledge of radiologists and non-radiologists about radiation doses of common radiological investigations. METHODS A prospe...

Investigations concerning the pre-radiological stage of silicosis.

Investigations of Positron Annihilation Radiation

By combining OSSE, SMM and TGRS observations of the galactic center region, Purcell et al. (1997) and Cheng et al. (1997) produced the first maps of galactic positron annihilation. That data-set has been augmented with additional data, both recent and archival, and re-analyzed to improve the spectral fitting. The improved spectral fitting has enabled the first maps of positronium continuum emis...

Radiation-related neoplasms, circulatory diseases, and cataracts among radiological technologists

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...
