The effects of usual low‐intensity continuous (Λ= 254 nm, I = 10 W/m 2 ) UV radiation and high‐intensity laser nanosecond (Λ= 266 nm, ‐τ p = 10 ns, I = 10 9 W/m 2 ) or picosecond (Λ= 266 nm, τ P = 23 ps, I = 10 12 W/m 2 ) 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.
