200 million datapoints!
A few days ago, Safecast reached a major milestone when our radiation measurement database reached 200 million data points. This database contains both mobile data collected using bGeigies and realtime data collected by our fixed systems. Our database has continued to grow so steadily over the past several years that, to be honest, we haven’t…
Over 300,000 data points gathered by #bgeigies4ukraine !
