Francesco Celani is a professor at the Italian National Institute of Nuclear Physics. He performed measurements on the Rossi device.
Sergio Focardi, emeritus professor physics, confirms what Celani said: there were gamma emissions during the functioning of the device. --- 00:23:37 | Focardi http://www.youtube.com/watch?v=S7lAlzMBzLQ&t=23m37s > During the first experiments, when we were working in Bondeno, we > were using an open experimental system, and on those occasions I was > using a Geiger detector, set for the gamma scale, through which I > verified the presence of gamma emissions during its functioning. -- Berke Durak
