RADICAL (RADIometric CALculator) is the program for calculating radiation characteristics of a gray thermal radiation source with uniform temperature, as well as radiation fluxes falling onto a detector from such a source. It is supposed that radiation heat transfer takes place in vacuum, i.e., without refraction, scattering, and absorption. RADICAL is intended for researcher working in optical radiometry, radiation thermometry, and similar areas; it can be used for educational purposes.
RADICAL works on PCs with MS Windows operating system (2000 to 7). Screen resolution should be not less than 1280 x 800 px.

RADICAL performs calculations of the following radiation characteristics of gray thermal sources:
 |
spectral radiance and radiance temperatures as a function of spectral variable |
|
position and value of spectral radiance curve maximum |
|
radiant exitance, radiance, and radiation temperature |
|
in-band radiance and in-band radiance temperature for a detector with the rectangular or Gaussian spectral responsivity shape |
|
irradiance distributions in the plane perpendicular to the axis of circular radiation source |
|
radiant flux emerged from the source |
|
radiant flux falling onto the circular detector which lies in the plane perpendicular to the axis of circular radiation source and co-axial with it |
RADICAL allows working with three spectral scales:
|
wavelength in µm |
|
wavenumber in cm-1 |
|
frequency in THz |
RADICAL allows working with three temperature scales:
|
absolute (Kelvin) in K |
|
Celsius in ºC |
|
Fahrenheit in ºF |
RADICAL provides a possibility to take into account the background radiation.
RADICAL presents results of calculations in tables and graphs. Numerical results can be saved in text files, XLS-files (MS Excel spreadsheets), and as XML and HTML tables. Graphs are fully editable and can be saved or exported as bitmap (*.bmp) or Windows metafile (*.wmf).
RADICAL has the mode of automatic selection of spectral range for graphs plotting.
