UVB band with the wavelength 280nm~315nm has the energy of 4.43eV~3.94eV

which can be calculated from Plank-Einstein equation.

In visible spectrum,light intensity can be calculated from

[tex] E_{r}=\frac{E_{0}}{4\pi r^{2}} [/tex]

With the above equation,when E(r) and E(0) is known,distance,r can be calculated.

Light radiation is measured in mW/cm^2,and I right?

So,my question is,using the above equation,instead of light radiation,

is it possible to calculate distance by replacing E(r) and E(0) with energy [eV] ?

Where E(r) and E(0) can be obtained from UV sensor readings.

Radiometers do measure UV intensity in mW/cm^2. I'm trying something different.
