Presettable synchronous 4-bit binary up/down counter

The 74HC191 is an asynchronously presettable 4-bit binary up/down counter. It contains four master/slave flip-flops with internal gating and steering logic to provide asynchronous preset and synchronous count-up and count-down operation. Asynchronous parallel load capability permits the counter to be preset to any desired value.

Tritium Fact Sheet - Health Physics Society

instruments, such as Geiger counters , are usually not capable of detecting tritium. The most reliable and widespread method for detecting tritium is known as liquid scintillation counting, typically available only in laboratory spaces. Tritium can also be “sniffed” or introduced into an ionization chamber that can measure radiation dose rates.
