Infectivity of PV-1 whole particle (closed squares) and PV-1 RNA (open squares) inactivated by UV. The regression equations with sample correlation coefficients (r) are also shown, where y is log PFU/milliliter and x is seconds. The UV doses at the respective time points were 0, 38.85, 77.7, and 116.55 mW · s/cm2 (0, 388.5, 777, and 1165.5 J/m2, respectively).
