Noninvasive measurement of current for dosimetry. Final report Aug 89-Aug 90
Minimally perturbing, resistive, non-ferrous probes were developed for measuring the current induced in personnel exposed to electromagnetic fields, with particular emphasis on the pulsed fields in electromagnetic pulse (EMP) simulations. Each of these probes has a nonferromagnetic toroid that passes around the leg or other body member, and a coil formed from high-resistance line that is evenly distributed over the full length of the toroid. A mental electrostatic shield is used to limit capacitive coupling. Active elements were not used in the probe circuitry so the probes have maximum ruggedness for use in high intensity EMP fields. These probes have sufficient bandwidth for time-domain measurements in EMP simulations. The probes are compatible with the low-impedance (50 ohms) fiber-optics transducers typically used for data acquisition in EMP simulations. Currents induced in humans nonferromagnetic toroid dosimetry specific absorption rate electromagnetic pulse.
