Fast method of determining the ambient dose equivalent at a depth of 10 mm of gamma-neutron fields based on recombination methods

The subject of the work is the presentation of a new measurement algorithm to be used in dosimetry, based on recombination chambers and methods. The algorithm enables fast measurements of the ambient dose equivalent rate H(*)(10) with a time resolution of several seconds. In addition to significantly reducing the measurement time, the method allows for the automation of the measurement with continuous evaluation of the results quality. Operating principles are based on frequent charge measurements with precise determination of the measurement moment. With well-known charge and measurement time, the ionisation current and therefore H(*)(10) can be easily calculated. The time constant of such a system is close to zero and allows to shorten the measurement time dozens of times while improving the quality of measurement by analysing the collected charge course.
