Summary

To transmit sounds from the High Radiation Level Examination Laboratory (HRLEL) cells, a simple, rugged, and inexpensive sound system was developed, fabricated, and tested. The massive shielding walls effectively attenuate the in- cell sounds needed to monitor operations and minimize ennui. To conserve cell space and minimize cost and maintenance, a single unit was desired to provide both general and local listening. Standard components were adapted to the needs and conditions of remote manipulation. An omnidirectional microphone unit with wide-range response and good fidelity was molded into a radiationresistant rubber jacket to aid in electrical coupling and protect against in-cell abuse. The pickup was connected to a wall jack, directly for general listening and through a specially designed jumper for local listening. The wall mount connected with an out-of-cell speaker that has a headphone attachment. Initial test results showed that use of the system in the HRLEL will reduce operator fatigue, decrease the need for equipment maintenance, and improve productivity. The design, criteria, operating performance, and cost of the portable system are presented with selected illustrations. (auth)
