Moderate Toxins · Brain health technique
Avoid unnecessary exposure to radiation and electromagnetic pollution (ionizing / non-ionizing)
Evidence grade: Mixed / Unclear

Ionizing radiation (X-rays, gamma rays, radon) directly damages DNA and brain tissue at high doses; non-ionizing electromagnetic fields (EMFs) from cellphones, Wi-Fi, or power lines produce low-energy waves that heat tissues slightly but do not break DNA. High-dose ionizing exposure is clearly harmful; non-ionizing risks remain uncertain, with most modern studies showing no consistent cognitive effects.

How to practice Avoid unnecessary exposure to radiation and electromagnetic pollution (ionizing / non-ionizing)
Avoid unnecessary high-dose medical or occupational radiation; otherwise, normal modern EMF exposure appears safe per current data. Per the NRC, limit your annual radiation to 50 millisieverts.
The evidence behind Avoid unnecessary exposure to radiation and electromagnetic pollution (ionizing / non-ionizing)
Ionizing radiation clearly damages DNA and brain tissue at high doses (cancer therapy, nuclear events). Evidence for non-ionizing EMFs is mixed, large population studies haven’t found consistent cognitive harm, though some small studies suggest subtle effects with intense local exposure.
