The Hyfrecator uses a spark-gap condenser circuit to produce a very high frequency damped current with high voltage and low amperage. The device has a White outlet for light power, a Red outlet for greater power, and Green outlets for bi-active techniques. Healing after electrodesiccation is usually complete in one to three weeks by granulation beneath the scab.

Electromagnetic radio-frequency fields and X-rays are considered harmful because they are invisible and not detected by sensory organs. Workers often underestimate the harmful effects of radiation. Currents above 50,000 cps do not pose electric shock danger, but burns from high-frequency heating installations are a risk. High voltages on electrodes present additional danger. The intensity of the electromagnetic field depends on the frequency of the generator and the distance from the radiation source to the operating location.

The rotation may tentatively not cause significant changes in gross morphology of pre-differentiated tissues. Root and shoot growth appears to have no orientation to the spatial coordinates of the medium and container.

Tolerable levels of 10 mw/cm² average power density for personnel and 5,000 mw/cm² peak power density for aircraft refueling were recommended. Insufficient information was available for HERO tolerable levels, safety regulations, protective materials, and measuring equipment. Pearl chain formation, Hall effect, and gaseous breakdown were found unsuitable for broadband sensors, while radiation pressure, absorption, and Kerr effect showed promise.

The study presented two units for electro-physiological investigations of the excitability of neuro-muscular preparations (n. ischiadicus and n. gastrocnemius) during irradiation with microwaves in the 10 cm range. A polystyrene chamber measuring 130 by 45 millimeters held the preparation during irradiation. The system included a unit for dosing the power flux density of the microwaves.

The study observed 20 poliomyelitis patients aged 13 to 50 years with disease duration of two months to one year and applied medium-wave diathermy (current strength 0.6 A, wavelength 300 m) to the lumbar bulge of the spinal cord at the pathological focus. Diathermy increased muscle excitability, producing tetanus within five minutes and raising contraction amplitude nearly threefold, with the effect persisting for 15–20 minutes after the session ended.
