Hot cells at the Glenn Research Center, Plum Brook Station
<ul><li>The Hot Laboratory at the Plum Brook Reactor Facility is shown in the late 1960's photo. Operators are shown working in what was termed the “Hot Cell Gallery,” using manipulator arms to handle radioactive test items inside a series of seven test cells. The operators became skilled at remotely operating the arms, shown in this photo as mounted on the right-hand wall, with black tops and light colored bottoms. The cells had fifty-two-inch, oil-filled glass windows and thick concrete walls to protect the operator from the radiation.</li></ul>
