Mosses as Bioindicator Of Radiological Contamination in The Nature Park Papuk

U prvim poglavljima ovoga rada opisana je kratka teorijska podloga o ionizirajućem zračenju, Parku prirode Papuk, poluvodičkim detektorima i visokorezolucijskoj gamaspektrometriji. Nadalje u radu su prikazani rezultati gamaspektrometrijskih mjerenja uzoraka mahovine uzorkovanih na području Parka prirode Papuk. Analizom rezultata koncentracije aktivnosti \(^{137}\textrm{Cs}\) i ovisnosti o nadmorskoj visini vidljivo je kako koncentracija aktivnosti \(^{137}\textrm{Cs}\) opada s porastom nadmorske visine. Analizom \(^{238}\textrm{U}\) i njegovih potomaka vidljivo je kako koncentracija \(^{238}\textrm{U}) i njegovih potomaka opada s udaljavanjem od površinskih kopova obližnjeg kamenoloma. Gamaspektrometrijskim mjerenjima utvrđena je prisutnost \(^{7}\textrm{Be}\) i \(^{40}\textrm{K}\)na svim lokacijama uzorkovanja mahovine.In the first few parts of this work it is given short theoretical introduction about ionizing radiation, Nature park Papuk, semiconductor detectors and high-resolution gamma spectroscopy. Furthermore, results of gamma spectroscopy measurments on moss samples collected on area of Nature park Papuk are displayed. Analizing results connecting concentration activity of \(^{137}\textrm{Cs}\) and elevation, it is shown that concentration of \(^{137}\textrm{Cs}\) is droping with growth of elevation. Analizing \(^{238}\textrm{U}\) and it's descendants, it is visible that concentration of \(^{238}\textrm{U}\)and it's descendants is droping with departure from nearby stonepits. Spending gamma spectroscopy measurments confirmed presence of \(^{7}\textrm{Be}\) and \(^{40}\textrm{K}\) on every location moss samples were taken
