Exposure Criteria for Non-Ionizing Radiant Energy in the Healing Arts
Sol M. Michaelson, William M. Houk · 1970
This 1970 report helped establish the first systematic approach to EMF safety standards in medical settings.
Plain English Summary
This 1970 technical report by Michaelson and Houk examined exposure criteria for non-ionizing radiation used in medical and therapeutic applications. The research addressed safety standards for electromagnetic energy devices used in healthcare settings during an era when such equipment was becoming more common. This work helped establish early guidelines for protecting both patients and medical professionals from potentially harmful radiation exposure.
Why This Matters
This foundational 1970 report represents a critical moment in EMF safety research when the medical community first began systematically addressing radiation exposure from therapeutic devices. What makes this work particularly significant is its timing - it emerged as hospitals were rapidly adopting new electromagnetic technologies without comprehensive safety protocols. The reality is that many of the exposure standards we rely on today trace back to this early technical work by Michaelson and Houk. Their research helped establish the framework for distinguishing between therapeutic benefits and potential harm from non-ionizing radiation in medical settings. This report also highlights how the medical establishment has long recognized the need for EMF exposure limits, even as consumer electronics have proliferated without similar systematic safety evaluations.
Finding
All of these radiant energies at certain frequencies, power levels, and durations of exposure can produce biological effects which may be beneficial. An example of this is the generation of therapeutic heat by modalities utilizing these energies. By the same token, the effects produced can be reversibly or irreversibly deleterious if precautions are not taken to protect patients and operators from over-exposure, Improper utilization, or inappropriate application of these medical tools.

Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
To analyze exposure criteria for non-ionizing radiant energy in the healing arts and to develop a rationale for safe limits for medical applications, distinguishing between general population exposure standards and those needed for diagnostic and therapeutic purposes.
Current standards for general population and occupational exposure are not applicable to medical uses of non-ionizing radiant energies. Medical personnel require theoretical bases and investigational data to develop criteria for safe limits within which they may work, or at least to evaluate a 'hazard-risk-benefit' problem rationally and in perspective.
