A non-resonant ESR instrument/probe that can easily accept an identification card (or the like) form factor device incorporating a radiation sensitive material providing reliable and calibrated dose measurement stably and permanently stored into the device and deployed to individual, persons, animals, or objects, to act as a personal-surrogate dosimeter primarily in radiation mass events with radiation dose derived from a measure of the radiation induced changes in paramagnetic density obtained via transmission mode electron spin resonance measurements.

Non-resonant electron spin resonant probe and associated hardware

A phase shift detector includes: an interferometer; and a microwave probe in electrical communication with the interferometer, the microwave probe including: a primary shield electrode; and a transmission electrode disposed proximate to the primary shield electrode, the transmission electrode and the primary shield electrode being exposed and arranged to produce an electric field, wherein the transmission electrode is isolated electrically from the primary shield electrode.

Phase shift detector process for making and use of same

An electron spin resonance spectrometer includes a bridge to transmit an excitation frequency and to receive a signal frequency; a probe electrically connected to the bridge and comprising: a first conductor in electrical communication with the bridge to transmit the signal frequency to the bridge; a shorting member electrically connected to the first conductor to transmit the excitation frequency to a sample, to produce the signal frequency, and to transmit the signal frequency to the first conductor; and a second conductor electrically connected to the shorting member; and a magnet disposed proximate to the probe.
