RF Cell Culture Irradiation System with Controlled Temperature and Field Strength,

摘要

A unique RF cell culture irradiation system with controlled temperature and field strength is described,which was used in determining human RF exposure thresholds in the frequency range D.C. to 100MHz. The system can produce electric field strengths up to 100 V/cm from D.C. to 1000MHz in a 5-ml sample of culture medium. The culture medium temperature can be controlled and measured up to 100MHz by monitoring the feedline impedance,which is dependent on culture medium temperature. Constant temperatures below 37C can be maintained at field strengths in excess of 25 V/cm. The information that can be obtained with the use of this system is needed to fill information gaps for standards criteria development.
