Simplified Approach for Preliminary Evaluation of Effective Dose Rates for Field Applications of D-T Neutron Generators

Portable neutron generators are one of the most widespread sources fast neutrons for different applications, from activation analysis to quantitative estimation fissile and fertile materials in radioactive waste packages. New techniques based on these devices have been developed homeland security, e.g. interrogations packages suspected containing substances such as explosives. When using portable determination radiation protection quantities is affected by a series boundary conditions that could differ an experimental set-up another, Radiation Protection Experts cannot assess operator exposure without aid time-expensive Monte Carlo simulations. As it impossible foresee all kind scenarios involving time often critical variable, safety assessment requires faster, even if less accurate, tools evaluation. In this article measurements dose rates real scenario D-T generator considered, validate model developed. Consequently, was possible demonstrate calibration factor at 14 MeV dosimeter provides conservative estimates propose stand-alone, fast, easy-to-use calculation tool which usable field Expert full calculations.
