The radiation level of the stack gases at the Brookhaven reactor is moni-
tored
by means of a Kanne ion chamber. This chamber is manufactured by the
General Electric Company at a cost of approximately $1,200. The connections to
the chamber are as indicated in the diagram below:

The function of the hold-up tank is to eliminate the effect of an unidenti-
fied
short lived activity.

A Beckman RXG-2 micro-microammeter is used to measure the output current
of the Kanne chamber.
