Re: [MW:21754] Iridium instead of selenium source

Hi,

You can take a trial (technique) shot employing all favourable factors to see if you can manipulate in the the required radiograph quality.

Ir-192 is hard for thicknesses mentioned. You may go for x-rays, your chances then are better.

Hi,

You can use Iridium192 with D3 or D4 films sensitivity you may achieve. Try this

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
