A thermoluminescence dosimetry system comprising a composite thermoluminescence dosimeter having a plurality of thermoluminescent elements fixed in a single frame consisting of a flat plate, each element being attached in a line to the frame in a thermally independent state from one another, means for heating each of said thermoluminescent elements one at a time by blowing a blast of heated air thereagainst, a readout instrument for measuring the thermoluminescence generating from said heated element and means for shifting said composite thermoluminescence dOsimeter to bring said thermoluminescent elements into a heating position one after another.
