Yes, exclamation dials had a less potent radium mix prior to the transition to tritium with the underline dial. That said, I would expect a reading in at least the higher single digits if the counter is placed correctly over the crystal. As a side note, the less expensive Radex counters that max out at 9.99 aren’t very useful for accurate readings on ‘60 and earlier radium dials imo.
