Fig. 7.

Detection of radioactivity using storage phosphor screens and a Typhoon scanner. (A) Comparison of radioactivity determined by the Typhoon scanner image versus counts per minute (cpm) detected using Cerenkov scintillation counting. (B) Image produced for a standard NAADP displacement curve using the Typhoon scanner . (C) Comparison of standard curves with radioactivity detected using scintillation counting (red symbols and line) and the Typhoon scanner (blue symbols and line). Error bars represent standard errors of the mean (n = 3). (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
