It's pretty credible to me: Here's the relevent part: Wallace's detector measures 36 neutrons per minute just in background radiation from space, and the device's usual output adds only four neutrons per minute. People in airplanes absorb much more than that.
In other words, the machine produces an output of neutrons that is barely over 10% of background levels. One neutron every 15 seconds is, well, not very many. "Notably absent is shielding," the article says elsewhere.
In contrast, if the cold fusion experiments were generating the heat they were said to generate from fusion, Pons and Fleischmann would have been promptly killed from all the neutrons that would have had to have been generated. Many, many orders of magnitude different.
At the recent MIT demonstration of cold fusion, FReepers were present,
and several presented, including a demo.
