What is Radionics?
Radionics is a practice that claims to diagnose illness and restore health by detecting and modifying subtle energy fields—purported electromagnetic or vibrational patterns emitted by living organisms. Practitioners use specialized instruments, typically featuring numbered dials, metal plates, and detection pads, alongside dowsing techniques (pendulums or “stick pads”) to identify energetic imbalances. Treatment involves “broadcasting” corrective frequencies back to the patient, often remotely using a physical “witness” such as a drop of blood, hair sample, or photograph. The practice operates on the premise that disease manifests first in these energetic fields before appearing physically, and that restoring energetic balance promotes healing.
Radionics is categorized as pseudoscience by mainstream medicine. Systematic reviews have found it no more effective than placebo, and the U.S. Food and Drug Administration does not recognize any legitimate medical use for radionic devices. The theoretical basis—that detectable subtle energies govern health—contradicts established principles of physics and biology. Despite this, radionics continues to be practiced in alternative health circles, particularly in the United Kingdom, and has applications in agriculture and veterinary care.
Origins & Lineage
Radionics originated in San Francisco with physician Albert Abrams (1863–1924), a University of Heidelberg graduate and former Fellow of the American Medical Association who had established himself as a prominent neurologist. Around 1909, Abrams began claiming he could detect disease by percussing a patient’s abdomen while they faced a specific direction. He theorized that diseased tissue emitted distinct “electronic reactions” that could be detected, quantified, and transmitted along wires. Abrams developed a series of devices—including the Oscilloclast and Reflexophone—to measure these purported vibrations and created the term “Electronic Reactions of Abrams” (ERA). He became a millionaire leasing these hermetically sealed instruments, which he refused to sell outright. A 1924 investigation commissioned by Scientific American definitively proved the devices ineffective, and the American Medical Association labeled Abrams the “dean of gadget quacks.”
Following Abrams’s death in 1924, chiropractor Ruth Drown (1891–1965) carried forward his work, developing her own nine-dial instruments and establishing the concept of “broadcasting” healing frequencies remotely using blood samples as witnesses. Drown also claimed to create X-ray-like photographs of internal organs using only a blood drop—images later attributed to psychic ability rather than any device function. She was prosecuted by the FDA and faced persistent legal challenges.
After World War II, radionics development shifted to Britain. George de la Warr (1904–1969), a civil engineer, obtained permission to replicate Drown’s instruments and discovered they functioned without electrical power, suggesting non-electromagnetic energy was involved. He and his wife Marjorie established Delawarr Laboratories in Oxford, conducting extensive research into radionic photography and developing over 8,000 diagnostic “rates.” Malcolm Rae (1913–1979), a Royal Navy commander turned radionic researcher, introduced the Magneto-Geometric system in the 1960s—geometric cards printed with magnetic ink that represented vibrational signatures based on angular relationships to Earth’s magnetic field. David Tansley (1934–1988) integrated radionics with concepts of subtle anatomy, chakras, and etheric bodies. Bruce Copen established laboratories in 1947 and manufactured instruments that relied primarily on pendulum dowsing rather than stick pads.
How It’s Practiced
A radionics session typically begins with a consultation where the practitioner gathers information about the patient’s health concerns. The practitioner places a witness sample (blood spot, hair, photograph, or even a written name) on the instrument’s input plate. Using a pendulum or by rubbing a detection pad (a rubber-coated surface that produces a “sticky” sensation when the correct dial setting is found), the practitioner tunes a series of numbered dials—usually three to twelve, scaled 0–10—to identify specific “rates” corresponding to organs, conditions, or energetic imbalances.
This process is understood as a form of radiesthesia or dowsing applied to health diagnosis. The practitioner mentally poses questions and interprets subtle tactile or kinesthetic responses. Once imbalances are identified, the same or a similar instrument is used for treatment: dials are set to rates associated with healthy function, and the device purportedly “broadcasts” these corrective patterns to the patient. Treatment can occur remotely over any distance, with the patient never physically present. Sessions may involve geometric pattern cards (Malcolm Rae’s system), homeopathic remedy simulation, or continuous broadcasting over days or weeks.
Modern practitioners increasingly describe radionics instruments not as functional electronic devices but as focusing tools for the operator’s intention and dowsing ability—a significant departure from Abrams’s original claims of measurable electromagnetic detection. The practice has expanded beyond human health to include veterinary care, agriculture (soil health, pest control, crop vitality), and the creation of vibrational remedies.
Radionics Today
Radionics remains a niche practice within alternative and complementary medicine communities, with the United Kingdom serving as its primary hub. The Radionic Association, founded partly by de la Warr, offers training and maintains professional standards. Manufacturers such as Copen Labs and Berkana Labs continue producing radionic instruments, ranging from simple two-dial analyzers to complex digital systems integrating software and remote broadcasting capabilities. Prices range from several hundred to several thousand dollars.
Practitioners typically work remotely, offering sessions via phone or email consultation. Some integrate radionics with other modalities: homeopathy, energy healing (Reiki, crystal therapy), herbalism, and naturopathy. In agriculture, radionics is used by organic farmers and biodynamic practitioners who claim it enhances crop yield and soil vitality without chemicals. India has seen growing interest in combining radionics with homeopathy for remedy potentization.
Radionics conferences, workshops, and certification programs exist, though credentials are not legally required or regulated. The practice occupies a contested space: openly practiced in parts of Europe, particularly the UK, but legally restricted for medical claims in the United States. Most seekers encounter radionics through alternative health directories, holistic practitioner referrals, or agricultural permaculture networks.
Common Misconceptions
Radionics is not electromagnetic therapy in the conventional medical sense. While legitimate pulsed electromagnetic field (PEMF) therapy uses precisely calibrated, measurable frequencies studied in clinical trials, radionics devices often lack functional electrical circuits and make no measurable electromagnetic output. The term “electromagnetic” in radionics refers to theoretical, unmeasurable “subtle” energies, not the electromagnetic spectrum recognized by physics.
Radionics devices are not diagnostic medical equipment. No controlled clinical trial has demonstrated that radionic analysis can accurately detect disease, and internal examination of historical devices revealed non-functional assemblies of wires and components. The “rates” used in diagnosis have no consistent correlation across different practitioners or instrument manufacturers.
Radionics is not universally accepted within alternative medicine communities. Many holistic practitioners, including homeopaths and energy workers, reject radionic claims as unsupported, and tension exists between those who view instruments as essential versus purely symbolic.
Finally, radionics should not be confused with radiesthesia (dowsing) itself, though the two are related. Radiesthesia describes the broader practice of using dowsing tools to detect subtle energies; radionics specifically refers to using instruments to both diagnose and broadcast healing patterns.
How to Begin
Those genuinely curious about radionics—whether from historical, anthropological, or exploratory interest—should approach with intellectual caution and awareness of the scientific consensus. Begin by reading primary historical sources: New Worlds Beyond the Atom by Langston Day (written with George de la Warr, 1956) provides the theoretical framework developed in British radionics. David Tansley’s Dimensions of Radionics (1972) explores the integration with subtle anatomy concepts.
For practical instruction, the Radionic Association (UK) offers structured training programs and maintains a directory of practitioners. Attending an introductory workshop allows hands-on experience with instruments and dowsing techniques under guidance. Organizations such as the U.S. Psychotronics Association host conferences where radionics is discussed alongside related topics.
Anyone considering radionics for health purposes should consult qualified medical professionals for diagnosis and treatment of serious conditions. Radionics has not been proven effective for any medical condition and should never substitute for evidence-based care. For agricultural applications, peer-reviewed research on soil health, organic methods, and biodynamic farming provides evidence-based alternatives to radionic claims. Approach radionics as a historical curiosity or spiritual practice, not a medical modality.
