OSL Reader

The OSL reader is a Landauer MicroStar reader. It uses a photo multiplier tube to count the hits off of the crystal structure in the OSLs when an LED is shining through it.

The measured dose is calculated through the following equation:

[math] \frac{PMT Counts}{(Calibration\ factor) (Sensitivity)} = Dose\ (mRad) [/math]

The low dose (10000 mRad>) calibration factor is 9.496494 as of 11/1/2017

The high dose (>10000 mRad) calibration factor is 0.6806084 as of 11/1/2017

The sensitivity is 0.92
