Investigating a Novel Psychoneuroimmunological Pathway: Natural Radioactivity as an External Correlate of Chanting NAM-MYoHO-RENGE-KYO

Aim: This observational study aims to explore a potential correlation between chanting Nam-Myoho-Renge-Kyo according to Nichiren Shoshu Liturgy and subtle changes in detected natural radioactivity, proposing a novel link to psychoneuroimmunological pathways. The study hypothesizes that the focused psycho-physiological state induced by chanting could modulate the immune system, with fluctuations in natural radiation serving as a measurable physical correlate of this biological process. Methods: Measurements of natural radioactivity were continuously conducted over multiple sessions using a RadiaCode 10X instrument in Mesa, Arizona, to record Counts Per Second (CPS), ambient dose equivalent rate (µSv/h), and energy spectrum during chanting and control periods. The analysis focused on variations in CPS and spectral data, with a single-subject, observational design. Results: The cumulative spectrum showed a prominent low-energy peak, consistent with background radiation. Quantitative analysis revealed subtle but consistent differences; a representative session showed higher total CPS during chanting (498,432) compared to the control period (471,680), a pattern observed across other sessions. Visual inspection also suggested a correlation between chanting and increased CPS variability. Conclusions: These findings suggest a link between a focused psycho-physiological state and subtle alterations in detected radiation patterns. While the mechanism remains speculative, this work proposes that the observed physical changes may be an external manifestation of an internal biological process capable of influencing the immune system. Further investigation is warranted to explore this potential connection, contributing to a deeper understanding of how the mind and environment interact to affect health. It acknowledges the spiritual depth of the Buddhist practice extends beyond scientific explanation, yet offers this as "actual proof."
