Measurements of 238U, 232Th, and 40K activity concentrations in some commonly used medicinal plant parts have been performed for radiation hazard assessment as baseline data health risk monitoring South Africa other countries. The mean was found to be 43.3 Bqkg-1, 33.7 180 Bqkg-1 Sclerocarya birrea; 85.0 75.3 316.7 Cymbopogon citratus; 47.3 37.0 773.3 Neorautanenia ficifolia; 25.7 30.0 510 Kige...

Personal protective equipment (PPE) refers to clothing and equipment designed to protect individuals from chemical, biological, radiological, nuclear, and explosive hazards. The materials used to provide this protection may exacerbate thermal strain by limiting heat and water vapor transfer. Any new PPE must therefore be evaluated to ensure that it poses no greater thermal strain than the curre...

Different methods of waste management emit a large number of substances, most in small quantities and at extremely low levels. Raised incidence of low birth weight births has been related to residence near landfill sites, as has the occurrence of various congenital malformations. There is little evidence for an association with reproductive or developmental effects with proximity to incinerator...

A Joint Working Group was established in April 1995 by the President of the Atomic Energy Control Board (AECB) and the Assistant Deputy Minister of the Health Protection Branch of Health Canada to examine the similarities, disparities and inconsistencies between the levels of risk considered acceptable for regulating ionizing radiation and those considered acceptable for regulating chemical and...

Artists may be exposed to a variety of potentially noxious materials. The modern techniques they use imply exposure to environmental hazards. Occupational health was evaluated in individuals engaged in different arts such as sculpture, painting, printmaking, restoration photography, glass-work and ceramics, because of exposure to toxic chemicals in art materials, tools and methods used in their...

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...
