Description
Car-borne gamma spectrometry and dose rate measurement are useful tools in various situations, such as geological surveys, searching for orphan sources, or surveying in the aftermath of an incident. The method can also be successfully applied for surveying large masses of NORM residues, since a great amount of NORM residue can be further reused, for example, as construction material. This usage, however, may be conditional on the necessity of effective dose rate estimation, which is where the car-borne survey can be extremely helpful.
Our presentation will introduce an experiment in which we compared different types of cars in order to assess the impact of different types of vehicle construction on the measured dose rate above a large mass of NORM residue. The experiment combines field measurement with Monte Carlo simulation. We compared the data obtained in various positions inside three different cars that were parked on a large source of NORM residue. The main point of the Monte Carlo simulations was to estimate the correction for a real-life situation, since our experimental source was notably smaller than real sources (such as roads built using NORM residues).
