The radiation exposure in the cath lab of patients, cardiologists, and nurses was measured during three consecutive periods of 8 weeks. The first 8 weeks the baseline radiation exposure was obtained. In the second period standard incidences for coronarography and frame rate were changed, without compromising the image quality of the examination. In the third period, a pelvic shield covered the lower part of the patient. This pilot quality project demonstrates that further significant reduction in radiation exposure of 37% is possible for patients. A significant reduction in radiation exposure of 53 and 62% was obtained among cardiologists and nurses working in the cath lab, even with the already diminished radiation exposure over the last years by better equipment and general radioprotection measures.

Purpose: We tested whether residents would improve in fluoroscopy knowledge and ability after using an inexpensive novel pelvis model and educational website.
Methods: Twenty-four orthopaedic residents were recruited from three United States residency programs and randomised into two groups with equal numbers of juniors and seniors. The OrthoAcademy group received educational materials from a website ( www.

The Hiroshima/Nagasaki (H/N) studies by the Radiation Effect Research Foundation have not shown increased leukaemia for acute doses below 200 milli-gray (mGy). By contrast the INWORKS study of leukaemia in workers stated: "This study provides strong evidence of positive associations between protracted low-dose radiation exposure and leukemia". The INWORKS study also claimed increased leukaemia, not including Chronic Lymphocytic Leukaemia, at cumulative occupational doses of less than 100 mGy.

The biological effects of electromagnetic field (EMF) irradiation in the terahertz (THz) range remain ambiguous, despite numerous studies that have been conducted. In this paper, the metabolic response of K 12 to EMF irradiation was examined using a 1.0 W m incident synchrotron source (SS) in the range of 0.

Exposure to high temperatures during indoor and outdoor activities increases the risk of heat-related illness such as cramps, rashes, and heatstroke (HS). Fatal cases of HS are ten times more common than serious cardiac episodes in sporting scenarios, with untreated cases leading to mortality rates as high as 80%. Enhancing thermal comfort can be achieved through heat loss in enclosed spaces and the human body, utilizing heat transfer mechanisms such as radiation, conduction, convection, and evaporation, which do not require initial energy input.

Introduction Orthopaedic surgery frequently involves the use of intra-operative radiographs, commonly taken with surgeons standing in close proximity to the X-ray machine. Radiation training and appropriate radiation protection minimise the harm that surgeons can face from ionising radiation. This study evaluates the current state of radiation training and protective equipment available to orthopaedic surgeons in the East of England.
