Resumen:
Un centro de investigación italiano ha desarrollado un sistema capaz de monitorizar residuos radiactivos en tambores en tiempo real. En Europa hay una gran cantidad de residuos radiactivos en lugares de almacenamiento temporales, donde se añaden residuos periódicamente. Los detectores desarrollados tienen una baja eficiencia intrínseca para que no se saturen fácilmente, y al mismo tiempo puede elegirse la eficiencia geométrica cambiando la longitud o espesor del detector. Los sensores de radiación son sencillos, fáciles de manejar, económicos y robustos. El centro de investigación busca socios con el fin de establecer acuerdos de cooperación técnica.

Technology for radioactive waste monitoring, in storage sites and in the environment
Summary:
An Italian research centre has developed a system capable of real time monitoring of radwaste on waste drum basis. The radiation sensors proposed are simple, cheap, robust, in need of a company available for marketing either the single sensor units or the whole system. in Europe there is a large amount of radwaste in temporary storage sites, with the periodic addition of newly produced waste. A partnership is sought for technical cooperation agreement.
Description:
All over Europe there is a large amount of radwaste in temporary storage sites, with the periodic addition of newly produced waste. In Italy there are currently about 27000 m3 of radwaste. The sensors system proposed can be used for low-cost special purpose environmental monitoring (for instance in order to check whether radioactive material is being smuggled into ordinary waste dumps).

The Italian research centre, operating in the fields of Nuclear Physics, has developed a real-time monitoring system for radioactive waste by using a prototype array of modular sensors based on a new kind of gamma mini-sensor based on silicon photomultipliers and scintillating fibers, that behaves like a cheaper scintillator Geiger-Muller counter. It can be placed in shape of a fine grid around each single waste drum dump.

The front-end electronics based on FPGA (Field Programmable Gate Array) counting system were developed to handle the field data, implementing also data transmission, a graphical user interface and a data storage system. Following a successful test of few sensors in a real radwaste storage site, a demonstrator system is currently being installed in a large storage site.

The research centre is looking for partners for technical cooperation agreement in order to exploit the technology in storage sites for real-time monitoring of radwaste.
Advantages and Innovations:
From a technical point of view a real-time monitoring of radwaste packages was already possible years ago, even though with some limitations.
Ambient radiation monitors are typically installed in several locations inside the storage sites. What one should do is replicate these systems in form of a mesh of detectors (i.e. Geiger counters) to be deployed all over the storage site around the packages and interconnected with an overall transmission and control system. This could work in principle but would pose a set of operational issues, first of all the cost.
The system proposed is a mesh of detectors to be installed on the drum platforms, capable of standing more than ten years close to a waste drum with dose rates of 10-100 mGy/h. Such detectors are robust, have low intrinsic efficiency, in order not to be easily saturated, but at the same time their geometrical efficiency can be flexibly chosen by changing the detector length or the thickness. The detectors are simple, reliable and easy to be handled, and cost less than -Y-euro;100/channel for mass production.
