Abstract
Albedo dosemeters for neutron individual monitoring are used worldwide and their response to the same dose can vary by more than one order of magnitude, depending on the neutron workplace spectrum. Two-component albedo dosemeters use two pairs of TLDs, one pair to measure incident neutrons (i) and another to measure albedo neutrons (a), used to corrections to the neutron HP(10). A Workplace Correction Factor (WCF) as a function of the i/a ratio can be plotted from experimental or simulated measurements. This paper uses a Monte Carlo MCNPX simulation of the Alnor albedo dosemeter response to plot WCF × i/a curves for several neutron fields. Experimental results were used to validate the simulation. The use of the proposed curves to calculate WCF can reduce the inaccuracies of the neutron dose assessment for different neutron fields of several facilities. However, it is necessary to be careful with the uncertainties of the i/a values.
