Re: [MW:21736] Iridium instead of selenium source

 Dear,

Using Selenium source we can achieve good sensitivity compare to Iridium source.

Because of low energy radiation, now most of the  International companies insisting selenium for low thickness materials.  otherwise we have to go for X ray.

Dear all,

My client asked for selenium  instead of iridium source upto thickness below  8 mm  field joint due to good sensitivity according to client specification.

Is it possible to do all the joint radiography below 8 mm thk. with iridium source with equivalent or better sensitivity changing the film quality or other variable.

Or any code reference iridium in lieu of selenium source

We are using D5 film.

Regards

Pradip
