AbstractAbstract
[en] The monitored radiation workers (n = 24) at 19 working places are exposed partially to significant increased concentrations of radon gas as well as radon decay products. According part 3 chapter 2 StrlSchV the required procedure of assessment of the radon exposure in self-responsibility of the responsible persons was verified. The results show differences between the estimated values on the one hand on the basis of personnel dosemeters and on the other hand on the basis of short-term measurements. In four of nine cases the values estimated with short-term measuring devices were lower as compared with long-term personnel dosimetry. In three additional companies can be observed overestimations as well as underestimations, if personnel and short-term dosimetry are compared. In the verified water plants the radon exposures are significantly below the action level. (orig.)

AbstractAbstract
[en] This review discusses the contribution of radiology to occupational medicine as well as work-related problems in radiology dept.s. Research issues are emphasized. Radiology has been used especially when diagnosing occupational respiratory and locomotive system problems and solvent-induced encephalo- and hepatopathy. The aim of research in these areas is usually to characterize occupational diseases and to identify physico-chemical hazards in the work place by comparing between groups of workers and non-exposed controls. Radiological imaging allows an objective characterization of the disease, and it may clarify the pathogenesis of the process and provide a useful epidemiological tool. Advanced statistical methods are often needed to adjust analyses for confounding variables. As the diagnostic requirements are increasing, more sensitive and sophisticated radiological methods, such as high-resolution computed tomography, magnetic resonance imaging and magnetic resonance spectroscopy, may be required for the early recognition of occupational health risks. This necessitates good cooperation between occupational health units and well-equipped imaging dept.s. Considering occupational problems in radiology departments, the increasing use of digital radiology requires ergonomic measures to control and prevent locomotive problems caused by work with computers. Radiation protection measures are still worth concern, especially in interventional radiology

AbstractAbstract
[en] Numerous workers are engaged in processing of tobacco in Iran and therefore, their exposures to tobacco dust are likely to be high. The aim of this study was to evaluate the workers' exposure to tobacco dust. Total dusts were collected within the workers' breathing zone using a Personal Air Sampler (PAS) and respirable dusts were measured using a real time monitor (Micro Dust Pro) with a particle size adapter in different parts of the factory. To weigh the filters a microbalance accurate to 5 decimal places was used. The mean total tobacco dust concentrations for personal exposure near breathing zone in this study was 9.32 mgm-3 that was lower than TLV recommended by American Conference of Governmental Industrial Hygienists (ACGIH). In contrast the mean respirable dust concentrations was 3.28 mgm-3 which is higher than Threshold Limit Value (TLV). Dust control methods such as good maintenance of existent dust emission control systems, insulation of dust sources and designing suitable local exhaust ventilation should be applied to maintain workers' health.

AbstractAbstract
[en] Purpose: Due to significant measuring inaccuracies that can occur under certain conditions, the use of electronic personal dosimeters in statutory measurements in X-ray diagnostics is currently legally restricted. The present study investigates the clinically relevant situations in which measurement errors of more then 20 % can be anticipated. Materials and Methods: Four series of experiments were made, comparing the results of the electronic personal dosimeter EPD Mk2.3 to those of reference dosimeters (TLDs and diagnostic dosimeters). On the one hand, personal doses have been determined in the routine operation of controlled areas in various departments. On the other hand, measurements on phantoms have been conducted in extreme but realistic situations under radiation protection. Experiments were conducted in unweakened scattered radiation as well as in unattenuated and attenuated direct radiation. Results: The tested electronic personal dosimeter type meets the requirements regarding measurement accuracy for 'official' personal dosimeters in all of the examined clinically relevant scattered radiation fields. Only if exposed to radiation directly, an underestimation of the dose can occur and can be greater than 90 %. Conclusion: In the range of scattered radiation of diagnostic X-ray equipment, even in pulsed fields, the use of electronic personal dosimeters is reasonable. Considerable measurement errors can only arise in radiation fields that are not realistic under regular conditions and even in connection with most accidents. (orig.)

AbstractAbstract
[en] Aim: The purpose of the present study is to describe and understand the meaning contents of radiographers' professional identity. Background: The conceptualisation of professional identity in terms of radiographers' perceptions of their role focuses on their preferred role-content and perception of the professional self. Professional identity defines values and beliefs that guide the radiographer's thinking, actions and interaction. Method: The present study employs the method of discourse analysis to gain a profound understanding of the cultural meaning contents related to the formation of the professional identity of radiographers. Material for the study was gathered from articles published in the professional journal of the Society of Radiographers in Finland between the years 1987 and 2003. Findings: Technical discourse emphasised the importance of responding to the changes in radiology in the 1990s. Safety discourse emerged as the second content of meaning describing the formation of professional identity. The third content of meaning in professional identity was professional discourse, a central aspect being to promote the esteem of one's profession and emphasise professional identity. Conclusions: The results suggest that the professional identity of a radiographer is dual in nature. On one hand, the professional identity of a radiographer is based on solid command of scientific-mechanic technology in a technical working environment; while on the other hand, it consists of mastering the humane, humanistic nursing work

AbstractAbstract
[en] The Zambian economy is dependent on copper mining,a metal, whose ore has a variable content of crystalline silica that has been noted to be as high as 30 to 40 per cent.The primary health concern in miners exposed to silica dust is wth the fibrogenic capacity of the inhaled silica particles that can lead to the development of silicosis.Inhalation of silica dust can can also cause chronic obstructive lung disease(COLD), lung cancer and increased susceptibility to develop pulmonary tuberculosis.This article is an outline of an epidemiological study of a cohort of Zambian miners whose goal is to build capacity to determine the risk of silica exposure leading to non-malignant lung disease and to build capacity to to implement interventions to reduce the risk of non-malignant lung disease among miners (author)
