Ionizing radiation as a topic of environmental education
VANĚČEK, Marcel
Ionizing radiation is a physical factor that has a significant effect on human health. An average person on Earth is irradiated at an average of 2.4 mSv per year. Most of this dose comes from natural sources, especially radon. High levels of radon are the second most common cause of lung cancer after smoking. At present there is an increase in exposure from medical sources which in some developed countries may equal to exposure from natural sources. Basic knowledge about sources of ionizing radiation, its effects and protection against it should be known to all high school students. The diploma thesis focuses on ionizing radiation from the perspective of high school teachers and students. It is divided into two main parts. In the first theoretical part the issue of ionizing radiation as a physical factor affecting human health is discussed. It describes the origin of ionizing radiation, basic concepts such as radioactivity and half-life, there are different types of radiation, individual sources, effects and protection against it. The second practical part is focused on examining the knowledge of high school students on this issue. The work tries to solve several goals. The first goal of the thesis is analysing the approach of high school teachers to information about the topic of ionizing radiation. The second goal is to verify the knowledge of high school students. The third goal is to evaluate whether high school students have a better knowledge of the topic of ionizing radiation than grammar school students. The fourth and last goal of the diploma thesis is to write a freely accessible material about the topic of ionizing radiation for high school teachers and students. This material will serve as an information source during the creation of the educational material for teachers teaching on the topic of ionizing radiation, but it can also be used by students while preparing seminar papers.

Allergens in the work enviroment
VANĚČEK, Marcel
The bachelor thesis on allergens in work environment is divided into two parts. The theoretical part, which describes the issue of allergic diseases, allergens and occupational safety from the general point of view and the practical part, in which the issue of allergic diseases arising in direct connection with the working environment is displayed using the data obtained. Four basic research questions were asked: "Which allergic diseases were most common in the work environment?", "Which allergens were most common in the context of allergic diseases?", "Which type of occupation was most commonly associated with allergic diseases?" What is the trend in the development of occupational allergic diseases?" The other 2 questions were focused on the links between allergenic substances and the work sector in which allergic occupational diseases occurred and the links between allergenic substances and the specific diseases that occurred. The bachelor thesis has been handled as a secondary analyse of data, these data have been granted by a Regional Hygienic Station in České Budějovice, department hygiene in work place. All the data included in this bachelor thesis were concerned all recognized illness from work in the South Bohemian Region from 2010-2018.
