NOTE 1 There is only limited evidence about effects for exposures of less than 10
-9
s for wavelengths less
than 400 nm and greater than 1400 nm. The AELs for these exposure times and wavelengths have been
derived by calculating the equivalent radiant power or irradiance from the radiant power or radiant exposure
applying at 10
-9
s for wavelengths less than 400 nm and greater than 1400 nm.
