Remarks

Originally intended for automatic calibration of the UD-710 automatic TLD reader. The design of this dosimeter is similar to the design of the UD-811 dosimeter except for encapsulation. Most users prefer to use the same type dosimeter for calibration as is used for routine monitoring of personnel and/or the environment.
