Claims13
A portable X-ray fluorescence analyzer, comprising a control unit and a detector of ionizing radiation, wherein:
- the detector of ionizing radiation is configured to detect at least one of:
- radiation from spontaneous radioactive decay within an environment of the portable X-ray fluorescence analyzer, and
- ionizing radiation propagating past a front end of the portable X-ray fluorescence analyzer towards its user;
- and the control unit is arranged to enable and disable an incident radiation source of portable X-ray fluorescence analyzer and is configured to disable said incident radiation source in remorse to a signal from the detector of ionizing radiation indicating presence of at least one of:
- radiation from spontaneous radioactive decay, and
- ionizing radiation propagating past the front end of the portable X-ray fluorescence analyzer towards its user.
A computer program product stored on a non-volatile computer readable medium, comprising computer-readable instructions that, when executed by a processor comprised in a portable X-ray fluorescence analyzer, cause the implementation of a method comprising:
- measuring at least one of:
- an amount of ionizing radiation from spontaneous radioactive decay within an environment of the portable X-ray fluorescence analyzer, and ionizing radiation propagating past a front end of the portable X-ray fluorescence analyzer towards its user, and
- as a response to said measuring, providing a signal that results ire disabling of an incident radiation source of the portable X-ray fluorescence analyzer.
