Effects of ultraviolet laser radiation on Venezuelan equine encephalomyelitis virus.
The effects of usual low-intensity continuous (lambda = 254 nm, I = 10 W/m2) UV radiation and high-intensity laser nanosecond (lambda = 266 nm, tau p = 10 ns, I = 10(9) W/m2) or picosecond (lambda = 266 nm, tau p = 23 ps, I = 10(12) W/m2) UV radiation on Venezuelan equine encephalomyelitis virus (a member of the Togaviridae family) were compared. The quantum yields of infectivity inactivation, pyrimidine dimer formation and RNA-protein crosslinking were determined.
