Several years ago, I measured one of the famous radioactive meters on a R-390 receiver and found only about 5x background with the probe against the face of the meter... a few inches away the count was greatly reduced. The clock on my Zenith G516W was only slightly higher than the R-390 meter.

I'm not worried about using the radio.
