Clinical profile

Baths with water containing low doses of radon. A meta-analysis of controlled studies and the RAD-ON02 RCT show pain reduction in rheumatic and degenerative diseases of the spine and joints; the effect appears after 3–6 months. Radon is a source of ionising radiation, and long-term residential exposure increases lung cancer risk.

Every statement links to a publication in the list below. This is a snapshot of published research, not a final assessment of the method: international practice and integrated protocols often run ahead of official publications. Draft based on published research; requires review by a physician. Revision: 2026-10-17.

Where studies show an effect

  • Rheumatic and degenerative spinal diseases, ankylosing spondylitis: less pain than in controls at 3 and 6 months after the course. [1]
  • Degenerative musculoskeletal diseases: radon baths give additional pain relief compared with warm water baths. [2]
  • Spinal osteochondrosis: pain reduction and increased mobility as part of rehabilitation. [3]
  • Upper respiratory tract diseases: procedures with radon water improved nasal flow and resistance. [4]

Open questions and study limitations

  • Immediately after the course there are no differences in pain from controls; at long-term follow-up in RAD-ON02, radon and warm baths reduced pain equally. [1, 2]
  • Rheumatoid arthritis: insufficient data that one type of bath is more effective than another. [5]

Safety

  • Long-term residential radon exposure increases lung cancer risk by 10–20 % per 100 Bq/m³; therapeutic doses are not comparable with residential ones, but radon remains ionising radiation. [6]
Contraindications. Contraindications are determined by the physician according to the equipment or drug instructions; they are not given in study abstracts.

Publications were found in PubMed; titles and journals are given verbatim, conclusions are a brief summary of the abstracts under the conditions of the specific studies. The level shows the volume of published data, not the value of the method: A — Plenty of data: consistent systematic reviews and meta-analyses of RCTs; B — Some data: reviews or several RCTs, results are heterogeneous; C — Little data: single RCTs or controlled studies; D — Scarce data: mainly reviews, observational and experimental studies. The passport is updated as new work is published and with regard to international practice.
