The radiation detector was fabricated from the TlBr crystals grown by TMZ (travelling molten zone) method and the FWHM and transit time of electrons and holes were measured as a function of temperature. The TlBr radiation detector shows the best response characteristics at about 313 K (3.19K-1) in cases where holes mainly contributed to the output pulses. However, in the temperatures higher than 300 K (3.33 K-1), the FWHM for 241 Am α-particles (5.48 MeV) becomes worse. An activation energy of about 0.90eV has been deduced from the resistivity measurement.
