PREDICCS accumulated dose as a function of aluminum shielding for the January events (Blue), March events (Red), and May event (Green). A power law (solid lines) is fit to the PREDICCS predictions. Dose accumulated by RAD (purple dots) is shown for each event (labeled at the right of each dot) at the average shielding of roughly 16 g cm⁻². In the lower-left corner are the mathematical forms of the PREDICCS predictions.
