Noise

Hello Radsafers:

While trying to trace the source of noise in our gamma spectroscopy system,
we observed a transient sinusoidal signal on our oscilloscope. We estimate
the frequency to be 0.9-1.0 MHz.
It appears to be a repeatable but not periodic radiofrequency signal.

Have you observed a similar phenomenon? Any ideas on the source of this
noise (we are in the basement of UCLA medical center)?      Any RF
shielding solutions?

Any help would be appreciated.

Sincerely,

Tim Paul + Olga Fernandez-Flygare
