Radiation Measurements

Evaluating measurement uncertainty of a physical quantity is a mandatory requirement for laboratories within the recognition ISO/IEC 17025 certification to access reliability of measured results. In this work, the uncertainty of ionizing radiation measurements such as air-kerma, personal dose equivalent Hp(d) was evaluated based on GUM method and Monte Carlo method. An uncertainty propagation software has been developed for evaluation of the measurement uncertainty more convenient.

The current paper discusses about the application of Monte Carlo method for the evaluation of measurement uncertainty using in-house developed program on C++ platform. The Monte Carlo method can be carried out by fixed trials as well as adaptive trials using this program. The program provides the four parameters viz. estimate of measurand, standard uncertainty in the form of standard deviation and end points of coverage interval as an output.

Number Of Classes

For the evaluation of measurement uncertainty in measuring the conduction emission, in this paper we propose a new model which uses mixed distribution. Evaluation of probability density function for the measurand has been done using Monte Carlo method and a modified least-squares method (combined method). In addition, the number of data n and the number of classes of histogram k which were used for simulation, were varied.

Method Of Calculation

The variant of Monte Carlo method for calculation of transfer of ionizing radiation having quanta energy of Eph=1-200keV is considered. The hybrid numerical and analytical method of calculation is offered. At numerical realization of each trajectory photo-absorption of quanta is considered analytically and other types of interactions (Compton and Relay scatterings, fluorescence) are realized in a random way. Calculations results for transfer of radiation having Plank spectrum are given for flat multilayered barriers.
