Fluorescence intensity calibrated with Resorufin solutions was obtained by the intensity integration of each image recorded every second (exposure time of 20 ms). This curve was obtained by using Ampliflu® Red at concentration of 5 × 10−5 M and sodium nitrate at 10−2 M aiming to scavenge hydrated electron. Beam intensity was roughly 2 × 104 α-particles per second
