October 17, 1951 TO: Clifford K. Beck FROM: Arthur Waltner SUBJECT: Stack Monitoring REFERENCE: Conference with J. E. Bins, Brookhaven National Laboratories, October 16, 1951

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.
