Risk Research: When Should We Say "Enough"?

Bioeffects Seen

M. Granger Morgan · 1986

Share:

After nearly 40 years, we're still asking the same question about power line EMF research sufficiency.

Plain English Summary

Summary written for general audiences

This 1986 paper by M. Granger Morgan examined when enough research has been conducted on 60-hertz electromagnetic fields from power lines to inform regulatory policy decisions. The study addressed the critical question of how much scientific evidence is needed before taking precautionary action on potential health risks from power line EMF exposure.

Why This Matters

Morgan's 1986 analysis remains remarkably relevant today as we continue wrestling with the same fundamental question about EMF research and policy. The reality is that nearly four decades later, we're still debating how much evidence is 'enough' to justify protective measures against power line magnetic fields. This paper appeared during the early years of serious EMF health research, when studies were beginning to suggest potential links between power line exposure and childhood leukemia. What this means for you is understanding that the regulatory hesitation we see today isn't new. The same questions about research sufficiency that Morgan raised in 1986 continue to influence how governments approach EMF protection standards, often prioritizing economic considerations over precautionary health measures.

Quick Questions About This Study

Morgan examined when enough research has been conducted on 60-hertz power line electromagnetic fields to make informed regulatory policy decisions about potential health risks.
It shows we've been debating research sufficiency for nearly 40 years, highlighting how regulatory hesitation continues to delay protective measures despite accumulating evidence.
Determining how much scientific evidence constitutes 'enough' to justify regulatory action involves balancing potential health risks against economic and practical implementation considerations.
The fundamental questions remain unchanged, but we now have decades more research showing potential health effects, yet regulatory agencies still cite 'insufficient evidence' for stronger protections.
It demonstrates that questions about research adequacy have long influenced EMF policy, often serving as justification for maintaining status quo regulations rather than implementing precautionary measures.
