Abstract
A method is reported to accurately and precisely control temperature of a solution sample to investigate non-thermal effects of radio frequency radiation (RFR) on pharmaceuticals. This method utilizes a transverse electromagnetic (TEM) cell connected in series with a radiation source. The temperature of a sample under study, within the TEM cell, is regulated using a combination of a fiber-optic thermometer and thermo-electric cooler. It is shown that the sample temperature can be accurately controlled and maintained even under conditions where the RFR can increase the sample temperature via thermal mode. This methodology provides a well-controlled approach to investigate the non-thermal effects of RFR for a range of incident power intensities and frequencies and initial sample temperatures.

Main findings
The authors report a method using a TEM cell with fiber-optic thermometry and a thermoelectric cooler to regulate solution sample temperature during RF radiation exposure. They state that temperature can be accurately controlled and maintained even when RF exposure would otherwise increase temperature via thermal effects, enabling investigation of potential non-thermal effects across incident power intensities, frequencies, and initial temperatures.
Outcomes measured
- Ability to accurately and precisely control/maintain solution sample temperature during RF exposure (to enable investigation of non-thermal effects on pharmaceuticals)
Limitations
- No specific RF frequencies, power levels, SAR, or exposure durations are provided in the abstract.
- No pharmaceutical endpoints or biological/chemical effect results are reported; the abstract focuses on methodology/temperature control.
- Sample size and experimental replication details are not stated.
