Sverdlovsk Regional Occupational Center based on the Research Institute has highly qualified staff, incorporates ambulatory department, hospital with modern diagnostic and therapeutic equipment. The Center performs multiple tasks, being an organizational and methodic, diagnostic and occupational examination institution using up-to-date advances in industrial medicine.
The authors represented integral evaluation of sanitary and epidemiologic well-being of people residing in coal miner towns. This evaluation plays an important role in formation of general including children's, occupational and infectious morbidity.
It will be clear from the aforegoing that occupational standards have varied over the past 30-40 years since the beginnings of the nuclear industry. Our perception of risk rates for cancer mortality and genetic effects has changed, such that the rates have been constantly revised upwards. Logically, dose limits should have been reduced in proportion, but this assumes a constant approach to the "tolerability" or "acceptability" of risk and this has not been demonstrated. Dose limits are not seen by management in the nuclear industry as the only plank in the structure of radiation protection; emphasis is also being given to the "optimization" ethic. In these circumstances a good test of the efficacy of the system of radiation control in limiting health effects is needed. As can be seen, no such study is available and, given the doses received and the numbers of workers involved, it is unlikely that any epidemiologic study, apart from studies on miners, will have sufficient statistical power to be totally unequivocal. However, some studies have shown cancer mortality associations with radiation exposure that are significant. Probably the best way to mitigate the inherent drawbacks in these studies is to pool data-sets, and this is being done. Other improvements will include estimates of cancer incidence in countries with cancer registries (e.g., U.K., Canada, and Sweden) and to perhaps go beyond epidemiologic data to consider sensitive biologic markers as indices of exposure. Overall the conclusion must be that the radiation industry cannot be complacent and for some tasks in the processes involved (e.g., uranium mining) there is strong evidence of a history of unacceptable health effects occurring.
BACKGROUND: It is unclear if objective selection of employees, for an intervention to prevent sickness absence, is more effective than subjective 'personal enlistment'. We hypothesize that objectively selected employees are 'at risk' for sickness absence and eligible to participate in the intervention program. METHODS: The dispatch of 8603 screening instruments forms the starting point of the objective selection process. Different stages of this process, throughout which employees either dropped out or were excluded, were described and compared with the subjective selection process. Characteristics of ineligible and ultimately selected employees, for a randomized trial, were described and quantified using sickness absence data. RESULTS: Overall response rate on the screening instrument was 42.0%. Response bias was found for the parameters sex and age, but not for sickness absence. Sickness absence was higher in the 'at risk' (N = 212) group (42%) compared to the 'not at risk' (N = 2503) group (25%) (OR 2.17 CI 1.63-2.89; p = 0.000). The selection process ended with the successful inclusion of 151 eligible, i.e. 2% of the approached employees in the trial. CONCLUSION: The study shows that objective selection of employees for early intervention is effective. Despite methodological and practical problems, selected employees are actually those at risk for sickness absence, who will probably benefit more from the intervention program than others.
Retrospective clinical and epidemiologic analysis covered occupational diseases in Leningrad region. Findings are that over recent years a tendency to lower number of primarily diagnosed occupational diseases continues. The authors justify necessity to work out the programs on prevention of occupational diseases in the region.
Higher occupational morbidity is not invariably a negative factor, sometimes being an indicator of good diagnostics and registration of occupational diseases, aimed to realize constitutional right for compensation of health damage caused by hazardous work conditions.
This study is devoted to the practice of the application of the current legislative regulatory and procedural base for the occupational health and safety issues. The issues of the occupational risks assessment at the enterprises of the Sverdlovsk region are discussed Approaches to the creation of the occupational risk management and assessment systems are proposed.
