Application of the small OSL elements to the ring type dosemeter

Miyauchi, Hideaki; Yoshitomi, Hiroshi; Takahashi, Fumiaki; Tachibana, Haruo; Suzuki, Akifumi; Sato, Yoshitaka*; Kobayashi, Ikuo*

In the Japan Atomic Energy Agency (JAEA), exposures to fingertips can be significant in radiological decontamination at the facilities with mixture fields of beta and $$gamma$$ (X) rays. The radiation doses to fingertips have been measured by ring type dosemeters equipped with thermoluminescence dosemeters (TLD) in JAEA. We applied small Optically Stimulated Luminescence (OSL) elements to the ring type dosemeter, which has the advantages in the use for long term and repeating in dose measurements comparing to the TLDs. The ring type dosemeter using OSL elements have started operating from 2012.

OSL and radiocarbon chronology of Late Quaternary sediments from Valley of the Gobi Lakes, Mongolia and implication to the glacier retreat in Khangai mountain range

Igarashi, Yudai*; Udaanjargal, U.*; Kokubu, Yoko; Watanabe, Takahiro; Hasegawa, Hitoshi*; Niiden, I.*; Katsuta, Nagayoshi*; Davaadorj, D.*; Hasebe, Noriko*

Lake Olgoy locates in the "Valley of the Gobi lakes" in southern Mongolia, on the southern slope of Khangai Mountain range. The 10.5 m core was collected from Lake Olgoy in the winter of 2017. This study measured quartz OSL, feldspar IRSL and radiocarbon ages. Quartz OSL ages range in 0.6$$pm$$0.1 ka to 10.7$$pm$$2.5 ka, feldspar IRSL in 1.1$$pm$$0.1 ka to 52.9$$pm$$5.0 ka and radiocarbon ages in 1.4 ka to 48.6 ka. Based on the comparison of ages by three methods, the age-depth model of the core was proposed. Together with other analytical data from the core, glacier melting events in Khangai Mountains will be discussed.
