The pitch of the columnar cholesteric mesophase formed by the dinucleoside phosphate d(GpG) and water becomes shorter after exposure to γ radiation. This effect can be measured directly with an optical microscope from the distance between the fingerprint lines. The inverse pitch is linearly correlated to the dose absorbed between 0 and 20 kGy.
