 Great!  I look forward to seeing those Geigers counters.

 Joohn Foote  is also interested, he will be doing a demo soon, so perhaps
we could organize a demo day for radiation stuff at NB.

I will wait to see  the general interest  before we set up a day and time.

 I will of course lots of drinks will also be part, no drinks no radiation.
