From: Dynamic fluorescence imaging of the free radical products of X-ray absorption in live cells
The first and last fluorescence images from a time series of live MEF cells taken before and during x-ray radiation. Many cells are visible in the field of view. The images are left) before the x-ray beam was switched on; right) at 5 minutes of exposure. The exposure dose rate was 3.0 Gy/min.
