This invention allows citizens to assess themselves (at the 2 Gy ± 0.5 Gy exposure level) using a dosimeter embedded in commercial and non-commercial identification cards. Patients can then seek appropriate action without the need for first responder and/ or public health official intervention. The
The new High Definition-E S R(HD-E S R ) spectrometer utilizes a superior detection scheme to perform electron spin resonance measurements. The major innovation centers on the use of a shorted coaxial “probe” (as small as a few nanometers) to excite the sample under test using near-field microwave

The detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a .change in effective dielectric constant of the sample. The major innovation
