I got an even "5 mR/Hr" reading from the 24 inch fluorescent tube. My homemade cathode ray tube got varying readings: 0 at the anode end, 20 mR/Hr in the middle of the tube, and about 5 mR/Hr at the cathode end. I also tried the survey meter on the induction coil itself with no bulb attached. Making a inch and a half spark between the electrodes, I buried the needle on the X1 scale. On X10 I got a steady 50 mR/Hr reading.When the coil is powering the Crookes tube or fluorescent, it does **NOT** spark.
The readings drop with distance too.* PBT _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
