Abstract
A portable analyzer comprises a detector of ionizing radiation that is configured to detect radiation from spontaneous radioactive decay within an environment of the portable analyzer and or ionizing radiation that propagates past a front end of the portable analyzer towards its user.
Claims20
A portable analyzer, comprising:
- a control unit;
- a user interface;
- and
- a detector of ionizing radiation that is configured to detect at least one of:
- radiation from spontaneous radioactive decay within an environment of the portable analyzer, and
- ionizing radiation propagating past a front end of the portable analyzer towards its user:
- wherein the ionizing radiation comprises at least one of alpha radiation, beta radiation, x-ray radiation and gamma radiation, and the detector of ionizing radiation is applied as a dosimeter that is arranged with the control unit and user interface to store and maintain a dedicated radiation log for each of a plurality of user accounts that enables monitoring of an accumulated radiation dose separately for each of said plurality of user accounts.
4 more elements
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 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 analyzer, and
- ionizing radiation propagating past a front end of the portable analyzer towards its user,
- as a response to a measurement that shows the intensity of ionizing radiation from spontaneous radioactive decay to exceed a predetermined threshold, producing an indication;
- storing and maintaining within the portable analyzer a dedicated dosimeter radiation log for each of a plurality of user accounts;
- and
- enabling monitoring via a user interface of the portable analyzer of an accumulated radiation dose separately for each of said plurality of user accounts according to the respective user account dedicated dosimeter radiation log;
- wherein the ionizing radiation comprises at least one of alpha radiation, beta radiation, x-ray radiation and gamma radiation.
