The intensity of radiation is illustrated by the image below. To calculate the intensity of radiation, three essential parameters are needed and these parameters are Transmitted Intensity (IT), Absorbed Intensity (IA) and Reflected Intensity (IR).
The formula for calculating the intensity of radiation:
Io = IT + IA + IR
Where:
Io = Intensity of Radiation
ITÂ = Transmitted Intensity
And also, IAÂ = Absorbed Intensity
IRÂ = Reflected Intensity
Given an example;
Find the intensity of radiation when the transmitted intensity is 8, the absorbed intensity is 10 and the reflected intensity is 4.
This implies that;
IT = Transmitted Intensity = 8
IA = Absorbed Intensity = 10
And then, IR = Reflected Intensity = 4
Io = IT + IA + IR
Io = 8 + 10 + 4
So, Io = 22
Therefore, the intensity of radiation is 22 W/sr.
Calculating the Transmitted Intensity when the Intensity of Radiation, the Absorbed Intensity and the Reflected Intensity are Given.
IT = Io – IA – IR
Where:
ITÂ = Transmitted Intensity
Io = Intensity of Radiation
Also, IAÂ = Absorbed Intensity
IRÂ = Reflected Intensity
Let’s solve an example;
Find the transmitted intensity when the intensity of radiation is 22, the absorbed intensity is 8 and the refleccted intensity is 4.
This implies that;

Io = Intensity of Radiation = 22
IA = Absorbed Intensity = 8
And then, IR = Reflected Intensity = 4
IT = Io – IA – IR
IT = 22 – 8 – 4
So, IT = 10
Therefore, the transmitted intensity is 10.

Calculating the Absorbed Intensity when the Intensity of Radiation, the Transmitted Intensity and the Reflected Intensity are Given
IA = Io – ITÂ – IR
Where:
IAÂ = Absorbed Intensity
Io = Intensity of Radiation
And then, ITÂ = Transmitted Intensity
IRÂ = Reflected Intensity
Let’s solve an example;
Find the absorbed intensity when the intensity of radiation is 18, the transmitted intensity is 2 and the reflected intensity is 4.
This implies that;
Io = Intensity of Radiation = 18
IT = Transmitted Intensity = 2
Also, IR = Reflected Intensity = 4
IA = Io – ITÂ – IR
IA = 18 – 2 – 4
That is, IA = 12
Therefore, the absorbed intensity is 12.
Calculating the Reflected Intensity when the Intensity of Radiation, the Transmitted Intensity and the Absorbed Intensity is Given.
IR = Io – IT – IA
Where:
IRÂ = Reflected Intensity
Io = Intensity of Radiation
Also, ITÂ = Transmitted Intensity
IA = Absorbed Intensity
Let’s solve an example;
Find the reflected intensity when the intensity of radiation is 10, the transmitted intensity is 4 and the absorbed intensity is 3.
This implies that;
Io = Intensity of Radiation = 10
IT = Transmitted Intensity = 4
Also, IA = Absorbed Intensity = 3
IR = Io – IT – IA
That is, IR = 10 – 4 – 3
IR = 3
Therefore, the reflected intensity is 3.
