I want to use the GMC-500+ to time the intervals between individual decay events of a Cesium-137 10 uci isotope disk. Is the GMC-500+ capable of capturing/sampling all of the decay events of this type of radiation source, and does the data it stores in flash provide timing of the events or not? I noticed on the GQ-RFC1201 protocol, the SPIR command will return historical data stored on the internal flash - however, I need the timing of each event with that data. Does the GMC-500+ provide this or not?
If timing data isn't captured on the flash, then my other question is, does the audio port on the 500+ provide the same data as an analog stream that is captured and digitized on the flash memory?
Thank you! |

| Hi balkanboy, yes it stores every decay it detects in the flash memory and can be downloaded using the Data Viewer software. It also stores a timestamp every 3 minutes. Yes the analog output is synchronized with the data stored in the flash memory. |

Does it store the timestamp for each decay event? |

| It depends on the mode. The default mode is every second. It will store every second data. So yes. You can also change it to every minute/hour. |

the data recorded in the Flash is the number of decay detected by the counter each seconds or minutes.
there are no timestamps especially for each detections.
To make it a random number generator, it's not really the ideal, after that depends on the desired dynamic or entropy level on this number and the acceptable observation duration.
With audio output, I do not know it more but seem to provides the detection shots, if it's connected to a external precision timer, then in this case we are in ideal conditions to generate a random number or sequence of uncorrelated random numbers .
there are some who use the electronic noise generated in resistances or diodes to generate random numbers, I have already heard that the decay were better and more efficient to do that. |
