Personal Radiation Monitoring Service
By Optically Stimulated Luminescence (OSL)

OSL Laboratory of Nagase (Thailand) Co., Ltd. provides the personal radiation monitoring service by using OSL type Qulxel for x-ray, gamma and beta radiation in term of Hp(10) Hp(0.07) and Hp(3). The dose report follows to international standard and displays the personal radiation dose for current period, annually and 5 years.

OSL dosimeter type Qulxel composes with 4 elements of Al2O3:C inside the badge with 4 filters (Open Window, Plastic, Copper, Aluminium) for radiation dose assessment and classify the type of radiation dose following to the energy response of Al2O3:C.

On the holder of OSL dosimeter is shown the detail as name of user, organization, period of using dosimeter and wearing position for convenience and information to user.

Detection capability of energies of OSL - Qulxel type

Type of Radiation Energy Range Dose Range
Photons >5 keV 0.01 mSv to 10 Sv
Beta >150 keV 0.1 mSv to 10 Sv
