UVB {photobiologyWavebands} | R Documentation |
Constructor of ultraviolet-B waveband
Description
Wavelength-range definitions for ultraviolet-B, UV-B radiation, by default according to ISO or as commonly used in different application areas.
Usage
UVB(std = "ISO")
Arguments
std |
a character string "CIE", "ISO", "medical" or "none" |
Details
Implemented definitions. UV-B according to CIE and ISO standrads: 280–315 nm. UV-B according to common non-standard practice: 280–320 nm. UV-B according to medical or dermatological non-standard practice: 280–320 nm.
Value
a waveband object defining a wavelength range.
Note
The non-standard definition of UV-B using 320 nm as limit should not be used in any new publications or work as it deviates from the internationally accepted standards and its use leads to confusion. Its inclusion in this package is to allow calculations needed to compare new results and methods against old publications.
