Nitrogen filled pressure vessels

Will X-rays have any effect on pressurized nitrogen in a pressure vessel. Mainly, can it increase the temperature of the nitrogen and increase the pressure? I do not think that it will but I have been asked this question by my client and I am now curious. He wants to send me some small spherical vessels that are pressurized to 6500 psi with nitrogen. The welds need radiographed. Any help will be appreciated.

Re: Nitrogen filled pressure vessels
Dear Fred,

I think there should not be any problem. The ionisation of nitrogen atoms/molecules that takes place will be reversed over a period of time, because it is a closed system.

The image sharpness could however be affected because of the scattering and secondary X-rays.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
