The ability to repair lesions is governed by second-order
kinetics with the limiting reactant being the specific chemical
initiating the repair process.Therefore,to overcome repair and
mutagenesis, the choice of UV source technology is critical.
High peak of UV power is preferred as it leads to the short
timed formation of excited DNA at concentrations above the
capability of repairing molecules.This is further discussed
below in Section Potential Uses of High-Power PUVC Radiation Sources.
