Abstract
In order to observe and evaluate easily the ultraviolet rays volume brought about by the formation of ozone holes, this paper aims at examining a possibility of observation of the ultraviolet rays volume included in the sunlight, using TLD and centering on the relationship between the exposure time and TL glow peak intensity. The contents are as follows: (1) Both principle of measurement and dosimeter with respect to ultraviolet rays volume are outlined, and the TLD used in the present experiment is mentioned.(2) With respect to measurement of the ultraviolet rays volume, TL glow curves after irradiating ultraviolet rays are considered.(3) Experimental procedure, result and examination are mentioned, and possibility of observation of the ultraviolet rays volume is confirmed
