Surface temperature from a radiation source

[gaz3787]

Hi all,

I am new to this forum and am a Biochemist. I am trying to do some basic calculations to understand the affects of a radiation source on a surface we plan to irradiate. We expect there to be little or no thermal effect due to the radiation source we are using however we would like to be able to clarify this with a basic equation.

I was wondering if one of you would be good enough to give me a helping hand in the direction I should go to work this out, baring in mind I have no previous experience doing such calculations.

A google search led me to these forums and I found these two threads

which are both linked to what i am looking at but with solar radiation.

Currently we know the time, we know the surface area, we know the energy and we know the wavelength of light we are using. IS there a basic equation to use to generate the heating affect?

Many thanks

Gareth

If it's light, then the scenario is completely analogous to solar. You equate power influx and outflow, and a surface temperature that solves the energy balance is the solution.

All radiation works the same as light does and calculations are the same.
