The goal of the project is the development of an integrated tool (instrument and methodology) to monitor continuously the marine radioactivity. The use of this tool by radioprotection agencies/organizations will promote their awareness before, during and after any radiological crisis. This project concerns:

1. The investigation of gamma-ray detection materials properties (type, size, geometry) by Monte Carlo simulations for optimization of energy resolution and sensitivity in marine radioactivity in-situ measurements,

2. The development of a new in-situ underwater gamma-ray spectrometer capable for low radioactivity level monitoring in continuous mode based on optimization techniques and, 3. The development of a methodology for automated acquisition by means of a new algorithm. This algorithm will automatically analyze the acquired data of the instrument providing radioactivity levels (in absolute units) of a marine area to the minimum possible time..
