Unidentified device

["Todd Brautigam" <brautt@myapc.com>]

Hi all,



At Maine Yankee, we have come across a device in a watertight canister that was apparently used to make a photographic record of water temperatures in the diffuser. Dose rates are ~ 0.2 mR/hr.



The neon green canister is 13 inches high by 6 inches diameter. The inside houses a small thermometer in the canister top, a camera lens, circuit board, a small DC motor to advance the film cartridge, and 2 battery holders.



Information on a tag inside indicate it came from Environmental Devices Corporation in Marion, MA. Attempts at contact to this point have not been productive.



Have you seen anything like this before?



I have pictures available if anyone is interested.



Thanks,





Todd Brautigam
