(optics)
A measure of the total radiant energy incident on a surface per unit area; equal to the integral over time of the radiant flux density. Also known as exposure.

The instantaneous irradiance multiplied by time duration of exposure results in the radiant exposure of the exposed specimens in the 295 to 385 nm spectral region expressed in MJ/[m.
Using these concepts, it is possible to calculate expected radiant exposure using the UAWS as well as compare radiant exposure rate using the UAWS with unaccelerated and moderately accelerated exposure methods.
Dividing the potential average yearly UV-radiant exposure using the ultra-accelerated device by the historical average yearly UV-radiant exposure on 45[degrees] south in southern Florida (17000/275), results in a radiant exposure acceleration factor of approximately 63 (approximately 56 for 5[degrees] South Florida).
A simple comparison of different types of exposures with ORWET shows correlation as a function of radiant exposure and acceleration as a function of time of exposure (days).
It was desired that the intensity on specimens be approximately an order of magnitude greater than conventionally accelerated weathering devices in order to study highly accelerated radiant exposures and the effects of significantly greater intensities.
Additionally, a much more diffuse sky dome in southern Florida (compared to Arizona) may help average direct and diffuse total solar radiant exposure, as shown in Figure 3.
Exposures at 5[degrees] in Arizona accumulated UV (ultraviolet) radiant exposure (dose) faster than at the 45[degrees] exposure angle in Arizona.
The significant differences in radiant exposure due to different exposure angles did not appear to cause significant effects in this experiment since exposure angle did not show a significant effect on the results.
