Research On Comprehensive Evaluation And Strategy Of Occupational Health Status Of A Uranium Purification Plant

Uranium purification process is an open radioactive job,the worker will receive alpha,beta,gamma irradiation inside and outside in the process of production.At the same time,some occupational harmful factors exist in some jobs such as dust,noise,etc,they are also harmful to the worker with non radioactive occupational injuries.To evaluate the quality of working environment of uranium purification workshop scientifically and reasonably,this article through to understand the production process of the enterprise of uranium purification plant,chooses the evaluation of the workshop divided in purification of the first line,purification of the second line and waste water treatment plant four evaluation units,then analyzes the potential occupational hazard factors and carries on the measurement,selects the alpha aerosol,gamma dose,noise,dust,ammonia and nitrogen oxides in six factors as evaluation index,through the analytic hierarchy process(AHP)to determine the index weights.Finally,gray correlation solution association degree and sort it.And this method will get each workshop occupational health condition of good and bad order.so as to better provide the scientific basis for occupational disease prevention and control.The result shows: the purification of the second line's comprehensive occupational health work environment best,the dissolution workshop followed,then the waste water treatment plant,the purification of the first line's condition worst.Finally,combining with the evaluation results put forward the corresponding measures to provide better scientific basis for occupational disease prevention and control.
