Christmas Light
’Twas the night before Christmas when all through the house
No electrons were flowing through even my mouse.
All devices were plugged by the chimney with care
With the hope that St. Nikola Tesla would share.

To investigate the feasibility of applying a porta-ble neutron generator for neutron radiography (NR), an underwater NR facility was designed and constructed in the water pool in a hot laboratory. By using the system, including neutron converters and films, it was possible to obtain NR images within ∼10 min. Various characteristic tests and photography by both emulsion and tracketch methods were carried out for various objects containing irradiated nuclear fuel samples. Some combinations of the converter and x-ray films, such as gadolinium foil/Type AA, were found to be suitable for NR in this case, but the much more sensitive converter NE426 was able to reduce the exposure time considerably. The strongly irradiated nuclear fuel samples were successfully photographed by CA-8015 track-etch films with a 10BN converter.
