### Abstract

The H_{p}(10) of an ideal TLD is independent of photon energy. This is to say that at any photon energy, the ratio R of the measured dose H_{p}(10)_{meas} to the delivered dose H_{p}(10)_{del} is always 1. In practice however the H_{p}(10) is dependent on the energy and R is not equal to 1. For this reason, ICRP has set the lower limit L_{L} and upper limit U_{L} for R as 0.55≤R≤1.63 for detection limit of 0.1 mSv and H_{p}(10)_{del}=1 mSv. As R is the quantity arises from the measurement processes, the existence of uncertainty of R, i.e. {increment}R is inevitable. In the boundary cases, such as when R is slightly lower than L_{L} or slightly larger than U_{L}, {increment}R would serve a useful quantity in decision making either to accept or to reject the value of R. The purpose of the present work is to estimate {increment}R for the TLD-100H for photon energy of 24-1250 keV. The estimation of {increment}R is based on the error propagation method. For the eleven photon energies, this work obtained (a) R in the range of 0.77 to 1.16, (b) {increment}R in the range of ± 0.02 to ± 0.04. The values of R were satisfactory as they complied the ICRP limit. The determined {increment}R is considered very small as it is in the order of 3% in comparison of R.
