The study of radioactivity and radiation problems and their comprehension by laical public
DVOŘÁKOVÁ, Romana
Radiation and radioactivity {--} these words awaken a sense of insecurity, unknowingness and sometimes even major concerns in many of people. On the other hand, only few people really have the right and sufficient information on this topic that is considered very important but also complicated and hard to understand. In my opinion, the majority of the public has no access to professional information on use of ionizing radiation and radioactivity. Therefore, they have insufficient knowledge of the topic and this fact results in concerns and fear of radiation that the public may hold. The hypothesis whether the amateur public is mainly afraid of medical sources of radiation, was determined for research in my bachelor thesis. Furthermore, I set several sub-hypotheses in order to gain a general picture of the points at issue and eliminate any ambiguous results. Moreover, the quantitative form of research was selected in order to reach the targets and verify the hypotheses. A questionnaire was used as a technique for collecting data. Members of the amateur public {--} patients of the hospital Mulačova nemocnice s r.o. in Pilsen {--} were selected as the statistical set for the purpose of the questionnaire survey. The objective of the thesis was to establish the concerns connected with various types of use of radioactivity and ionizing radiation, provide the objective and coherent perspective of the level of the amateur public{\crq}s awareness in this field, and propose the most effective way of presentation of information in order to spread the general awareness based on the data acquired and statistically processed. I would like to provide my bachelor thesis as a source of information to the general public. Furthermore, I would like to offer the results of this thesis to organizations dealing with these points at issue and as a course material for students of the University of South Bohemia in České Budějovice.
Confrontation of radiation dose of professional in nuclear medicine department in Hradec Králové before and after installation PET/CT, possibilities of monitoring
JANSOVÁ, Martina
This Bachelor Thesis deals with the radiation load of Nuclear Medicine employees of University Hospital Hradec Králové before and after the introduction of PET/CT examinations. Compared with usual examinations with gamma emitters and therapy with open beta emitters, the PET/CT examination method uses positron emitters and is carried out at the Department of Nuclear Medicine of University Hospital Hradec Králové (DNM UHHK). The use of positron emitters leads to increased demand in respect of radiation protection and work organisation. I made an evaluation of doses from personal dosimetry from 2004 until 2008 prior to the introduction of the PET/CT examination methodology; and year 2009 is subsequently assessed in respect of the situation after the introduction of PET/CT examinations. The results of doses are provided in tables. Film dosimeters and thermoluminescence (TL) ring dosimeters had been used for personal dosimetry until 2008. Digital dosimeters have been also used for personal dosimetry since 2009, and they are further included in the comparison of the received radiation doses of employees. The results were used for an evaluation of optimisation of radiation protection at the DNM UHHK.
