Notes:

• Lab setup (photo details):
  • Connect the USB cable from the Radiation Monitor to the Dig/Sonic1 port
  • The Chart of the Nuclides are stored in a cardboard tube sitting at the edge of the shelf (photo)
    • There are many editions of the charts in the tube. Be sure to use the newest ones (Seventeenth Edition - Revised to 2009 - photo)
