Solid State Radiation Detector with LCD Complete!

I added a PIC and LCD to my basic radiation detector and can now display total counts over time(up to 24 hours) or Counts/Sec and relative gamma strike energy level. The energy level varies as every gamma strike does not dislodge the maximum possible number of charge carriers. I take the maximum value registered every second and display. On average various materials indicate different levels, providing a crude detection signature. Besides the LCD display, this circuit has a sample and hold circuit which  is connected to  the PIC ADC module and also tied a another PIC I/O pin which switches from tristate to pulled low to reset the sample/hold circuit. The maximum sample rate is 13500 samples/per sec.
