2019年12月14日 · The OSL dosimeter provides a very high degree of sensitivity by giving an accurate reading as low as 1 mrem for x-ray and gamma ray photons with energies ranging from 5 keV to greater than 40 MeV. OSL dosimeters are designed to provide X, gamma, beta and neutron radiation monitoring using OSL technology.

In physics, optically stimulated luminescence (OSL) is a method for measuring doses from ionizing radiation. It is used in at least two applications: The method makes use of electrons trapped between the valence and conduction bands in the crystalline structure of certain minerals (most commonly quartz and feldspar). [1] .

2022年2月1日 · A laser based Optically Stimulated Luminescence (OSL) reader is designed and developed for its application in OSL based radiation dosimetry. The system provides the facility to record CW-OSL at two stimulation wavelengths of 442 and 532 nm (Δλ ± 2 nm) respectively.

2022年1月1日 · OSL is the emission of light from an irradiated semiconductor (wide band-gap) or insulator material during optical stimulation. Irradiation with ionizing radiation creates free electrons and holes in the material. Some of these electron-hole pairs can be captured by defects of the material which are called traps. These traps are deep enough to ...

2021年11月21日 · In this study, a laboratory pilot of an OSL dosimetry system was designed and built for use in remote radiotherapy dosimetry. In the design and construction of this dosimeter, optical and electronic noise removal considerations have been considered.

2023年11月3日 · Optically stimulated luminescent dosimeters (OSL) are passive radiation detection devices used for personal dose monitoring. Unlike thermoluminescent dosimeter (TLD). OSL does not need heating for the reading of radiation dose. OSL dosimeters can be read multiple times and stored for several years 1.

2014年12月1日 · We discuss factors that made the OSL technique successful: its simplicity, accuracy, wide dynamic range of measured dose, ease for automation, re-read capability, ability to perform imaging, and the availability of diverse instruments and materials.

Since 2000, LANDAUER have adopted the use of the OSL (Optically Stimulated Luminescence) technology for assessing personal dose in particular with Luxel+®. OSL has been developed using material manufactured by LANDAUER to its own specifications: aluminium oxide doped with carbon (Al 2 O 3:C).

Optically stimulated luminescence (OSL) dosimetry is a well-established method of reporting individual doses. Our new OSL dosimeter defines a milestone in monitoring the Personal Dose Equivalents H p (10) and H p (0.07).

OSL stands for optically stimulated luminescence, and dosimetry measures ionizing radiation dosages. It allows for measuring exposure to radioactive isotopes over a specific time. Many agree that OSL dosimetry is a better alternative to …
