Study type: Medical/biological study (experimental study)

Studies of exposure of rabbits to electromagnetic pulsed fields. med./bio.

Published in: Bioelectromagnetics 1980; 1 (3): 345-352

Aim of study (acc. to author)

To investigate the effects of electromagnetic pulsed field exposure to rabbits.

Background/further details

Parameters studied were pentobarbital-induced sleeping time, rectal temperature measured immediatly pre- and post-exposure and several serum parameters (among other things triglycerides, creatine kinase isoenzymes, sodium, and potassium).

General information

Experiment 1

Exposure 1

Main characteristics
Frequency 23.5 MHz
Exposure duration continuous up to 2 h
Modulation
Modulation type pulsed
Pulse width 400 ns
Rise time 100 ns
Repetition frequency 10 Hz
Exposure setup
Exposure source
  • EMP simulator consisting of two copper sheets, 61 x 114 cm
Exposure room EMP stimulator
Setup Four styrofoam panels were placed between the plates to restrict the animals to the central region of the exposure chamber. Animals were placed in the center of the chamber on a plexiglas sheet
Additional info The sheets were configured in such a way that the horizontal section used to expose animals had dimensions of 56 cm x 61 cm and a plate seperation of 19 cm, where as the remaineder of the plates section 58 x 61, the gap was narrowed to 6.4 mm and filled with polyethylene to provide capacitance. The EMP stimulator was located in a faraday cage.
