Gamma Dose Rate Values In The Kulakçayiri Natural Lake And The Vicinity (Arnavutköy, İstanbul)

Abstract

With the formation of the world, the radioactivity affected humanity throughout history. The

rock beds beneath the soil layer forming natural radioactivity are sources of terrestrial radioactivity.

Environmental gamma radiation consists of terrestrial and cosmic sources. The gamma dose rate

method is used to determine the radiation emitted by the terrestrial radiation. In this study, the gamma

dose rates were determined by conducting measurements at twenty points at intervals of 12 km from

Kulakçayırı Lake and its vicinity. Open gamma doses in the air at a height of 1 meter above the ground

level were measured using a portable gamma scintillation detector. The measurements were made once

per hour. The average gamma open dose values measured at 20 locations measured per hour in the air

at an altitude of 1 m was 37.5 nGy / h.
