[MW:1215] How to reduce the exposure time for RT

Dear Group,

 

I need help to find out how to reduce the exposure time for heavy wall thickness RT (above 4" thickness and ID of vessels 4 meter) .

 

Composite film is one of the option. Any other idea ?

 

I heard from my client that there are accelerators available which can be used for developing the film to compensate the reduce time of exposure.

 

We are using Co-60.

 

Regards.

CK
