Tube Deteriorated Quickly

I've been running one of these for about three months and the device is starting to have problems. First, about a month ago, the tube became very photosensitive. This was unexpected, since the tube was not photosensitive when it arrived. However, the M4011 is known to be photosensitive, on a tube by tube basis; some are, some aren't.

After rebuilding my enclosure to place the tube in darkness, it worked OK for a few more weeks, but now it is failing to quench properly, resulting in bursts of 2 to 10 pulses within 2 to 5 milliseconds. My guess is this is not unusual for these cheapo tubes. A reminder that this is a toy, not a real instrument. Although it can be used to demonstrate *approximate* background radiation levels, and the inverse square law with a weak radiation source.

To work around this I modified my code to ignore pulses less than 10 ms after the preceding one. This seems to provide reasonable counts again, although the background level is about 25 CPM instead of the 20 it was when the tube was new.
