Radiation

Introduction

Radiation is the diffusion of electromagnetic waves of particles in the space. A kind of radiation is the ionizing radiation, which is able to penetrate easily the matter. Under controlled conditions, ionizing radiation can be used in several experiments to measure properties such as void, flows, density, or composition.

The Radioactive Particle Tracking (RPT) mainly uses gamma sources to measure the energy release by a radioactive source. The basics idea behind the RPT is attenuation of the gamma rays. It means that the closer a gamma source is, the more particles are detected. This principle helps out to measure flows inside opaque ducts because conventional techniques do not have this capability.

The simulation of the RPT experiment is achieved by splitting the trajectory in discrete points and recording the detector response. This is saved and used in algorithms to reconstruct the particle trajectory.
