Description/Abstract:
The operation of two constant air monitors in Building 706-D, one on the 2nd level over the hot laboratories and one in the center of the third level, are discussed. Calibration testing showed that the sensitive region of the GM tube was not properly centered with the length of the slot since readings at the top and bottom of the slot are not equally less than the center and the energy response is seen to be different by an average of a factor of 2 compared to another instrument. Computations are included.
