The radiation exposure of the employers in Jachymov Spa
STRAKOVÁ, Eliška
Jáchymov radon spa, which is the subject of this bachelor thesis, uses, besides classic spa methods and balneological procedures, the radon water treatment. The main goal of this thesis is to get familiarised with the spa and empirically evaluate radiation exposure of spa employees. In the theoretical part, I define (theoretical basis) basic concepts, on which the problematics of this thesis is based. In another part I deal with the history of the spa complex, origin of therapeutic sources and their utilization. Also, as a part of this thesis, I mention illnesses, indicated for this type of treatment and clarify principles and effects on the basis of documentable research from literary sources. Because the thesis is focused on radiation exposure, in other chapters I deal with radiation protection and monitoring of doses (of radiation) of staff present in the spa. Practical part is focused on empirical quantitative research, aiming at statistical processing of data for development monitoring. The main idea is to process radiation exposure of employees in the timeframe of 26 years, between years 1991 - 2016. Furthermore to evaluate the development with closing general comparison of the processed results between spas, utilising radon water treatment and employees of uranium mines. Statistical processing shows that development of received doses is periodically fluctuating. The average value of effective dose was found to be 2,39 mSv in all employees with the highest possible received dose of 10,23 mSv per year. In case of equivalent dose to the skin was the average value 1,70 mSv per year. Despite the dose values being fairly high, it can not be said that radon spa employees exceed limits of radiation protection.
