Why it's stuck
Ultra-fast dose delivery seems to protect normal tissue, but nobody has settled why. Simulating the chemistry at these dose rates is very expensive, so it is done at small scale.
What we'd try
Run large simulations of the chemistry at FLASH dose rates to test the competing explanations against measured data.
What could stop us
Several groups already run large FLASH radiolysis simulations, and the real bottleneck may be biology rather than chemistry compute.
