Radiation Detection

A radiation detector has a detection module, a processing module, and a display module. The detector resolves incident radiation as an energy spectrum. The data is numerically processed e.g. Bayesian deconvolution, chi-squared minimisation or iterative forward method to produce a further spectrum and measure of incident radiation such as dose. A statistical test such as T-test, Poisson error or confidence limits is applied to the further spectrum or dose data to calculate an uncertainty measure. A display produces a bar or pie chart indication of both dose and uncertainty. The apparatus is described as portable and capable of being used with mobile communication devices.
