Measurement of Electromagnetic Fields within Bulk Materials by Means of the Moessbauer Effect.
Abstract
The internal electromagnetic field of bulk objects being irradiated with radiofrequency (RF) radiation is often a necessary parameter for assessing potential radiation damage, particularly in the case of biologic entities. At present, most methods of measurement require some form of communication leads to an embedded probe; however, since these leads may serve as antennas, the local RF fields are frequently disturbed. Another approach could be the implantation of an intermediate frequency transmitter to telemeter the probe measurement. Excessive size makes such devices impractical. The shortcomings of the use of probes can be overcome by an application of the Mossbauer effect. Presented in this report are a description of the Mossbauer effect and how it can be applied to RF field measurement, a system design for establishing the Mossbauer-effect experiment, and some preliminary results.
