小線量γ線による自己免疫疾患治療への可能性と題する既報があり，これを踏まえラドン吸入による自己免疫・炎症性疾患の症状改善とその応用の可能性について関連研究成果の一部概説と提案をした。その結果，小線量γ線照射と同様に，Th1系・Th2系・Th17系の免疫応答をバランス良く制御したことなどから，ラドン吸入は抗炎症・免疫調節作用やこれに伴う自己免疫・炎症性疾患の症状改善に効果のあることが示唆できた。また，新型コロナウイルス感染症（COVID-19）の症状改善への応用の可能性について，ラドン療法と抗リウマチ薬や実用治療薬との併用効果の検討を提案した。
Previous reports have suggested the potential of low-dose γ-irradiation for treating autoimmune diseases. Building on this, we reviewed relevant research findings and proposed the potential application of radon inhalation for improving symptoms of autoimmune and inflammatory diseases. The results suggested that radon inhalation, similar to low-dose γ-irradiation, effectively balances Th1, Th2, and Th17 immune responses. This indicates its potential anti-inflammatory and immunomodulatory effects, along with associated symptom improvement in autoimmune and inflammatory diseases. Furthermore, regarding its potential application for improving symptoms of COVID-19, we proposed investigating the combined effects of radon therapy with anti-rheumatic drugs and practical therapeutic agents.
Key words: radon inhalation; immunomodulatory and anti-inflammatory effects; autoimmune and inflammatory disease; COVID-19
