RT of hydrogen pipeline

Hello,

I would like to undertake RT using Ir 192 of a cirseam weld of a hydrogen pipe of about 8 mm thick Carbon Steel when Hydrogen is flowing inside. The pipe is at room temperature.

Is it safe ? Any guideline available ? Anyone having prior experience ?

Thank you

Ananthan

General discussion & idea
Radiography principle differnetial absorption and scattering of radio waves to differnet material density.
Hydrogen in gas state will be more than denser than normal air, but it will not affect the RT images as water inside the pipe, Safety point Hydrogen to b discussed

Re: RT of hydrogen pipeline
It is agreed that hydrogen will have no effect on the image quality, but it is less dense than air and explosive.
Radiography should pose no safety issues. (Assuming the pipe is not leaking).
