Abstract: The instant invention provides in-vivo methods and apparatus for radiation dosimetry assessment in individuals exposed to potentially harmful radiation, based on measurements in-situ of the teeth. The in vivo dosimetry assessment methods and apparatus utilize electron paramagnetic resonance (EPR) techniques; and employ an apparatus comprising an integrated EPR spectrometer system, an ergonomic magnet and a constructed resonator structure. In various aspects, the dosimetry assessment apparatus is configured to be easily portable and withstand potentially adverse mechanical effects of transportation and deployment in the field. The apparatus also is configured with a power supply that is compatible with both conventional AC line voltages and/or other sources of power suitable for field conditions; and may be easily operated by minimally trained technicians to quickly generate a readout of estimated radiation exposure dose.

Abstract: A portable superabsorbent personnel stretcher and exactable on-demand isolation tent article is provided which is easily transportable, durable, and can be prepared in both sterile and non-sterile formats. The combination superabsorbent stretcher and isolation tent provides a fluid-absorbing capacity and capability via fibers able to absorb at least 15 times their own weight in fluid. The invention also provides portable means for erecting the collapsed isolation tent on-demand and portable means for transporting the combined stretcher and isolation tent in both collapsed and erected states.
