Abstract
The pressure of a gas in a closed vessel can be non-destructively read by irradiating the closed vessel with x-rays. The irradiated gases in the vessel emit x-rays characteristic of various gases within the vessel. The characteristic x-rays, which pass out of the vessel, are discriminated and their intensity count converted to a pressure reading.
