摘要

The Dead Sea is a giant, super-saline lake at the lowest spot on Earth. And its beaches appear to be pebbled with perfect little cubes of sodium chloride crystals. This inorganic crystal presents the thermally stimulated luminescence and then is useful to detect the ionizing radiation. This The Dead Sea Crystal (NaCl) were tested under beta low doses from 50 to 750 mGy from ~(90)Sr at UNAM. The aim of this paper is to analyse the thermoluminescence (TL) response of the NaCl crystals under irradiation at room temperature. The results from TL experiments relevant to space dosimetry applications, such as dose response, reproducibility and lost signal are described. The behaviour of the TL signal observed was found to be favourable for monitoring low doses on the crew present at spaceship, with both the dose response and fading suggesting a range of at least 750 mGy. In turn the samples show an abroad glow curves and high TL intensity. The maximum temperature of the glow peak was observed at 220 °C. In this last case, a linear TL dose-response between 50-750 mGy was observed. The Dead Sea crystals should be useful to use as natural passive detector also in order to prevent and monitoring the radiation damage in the environment radiation conditions of the spacecraft.
