ABSTRACT:
A thermoluminescence dosimetry (TLD) card reader includes at least one light detector for detecting light emitted by a heated thermoluminescent element and a heater for heating each TL element. The heater includes a conduit for channeling a flow of gas from a gas source and for discharging heated gas against a TL element, along with means for heating the conduit for transferring heat from it to the gas flowing through it. Preferably, the conduit is electrically conducting and an electrical current is passed through it via leads joined to the conduit near its inlet and outlet ends to heat the tube. A thermocouple disposed proximate the outlet end of the conduit for measuring the temperature of the gas being discharged from the tube, provides an electrical signal to a controllable electrical current source connected to the leads so that the temperature of the gas being discharged from the conduit may be controlled according to a prescribed relationship.
