Researchers exposed human bone marrow cells from leukemia patients to 2450 MHz microwave radiation (the same frequency as microwave ovens and some WiFi) at various power levels for 15 minutes. They found that higher power exposures significantly reduced the cells' ability to form colonies, suggesting direct cellular damage. This demonstrates that microwave radiation can interfere with human blood cell production at the cellular level.

Finnish researchers measured electromagnetic field emissions from 35 industrial plastic welding machines operating at 27 MHz with power outputs up to 35 kW. They found that 70% of these radiofrequency heaters exceeded common international safety standards for electric field strength, and 80% exceeded Finland's proposed stricter standards. This study reveals significant workplace EMF exposures from industrial heating equipment that often go unmeasured.

NIOSH researchers measured radiofrequency radiation exposure levels among 82 workers operating RF dielectric heat sealers across 13 facilities. They found that 84% of operators were exposed to electric field levels above NIOSH's proposed safety standard, with some exposures exceeding the limit by more than three times. This workplace study reveals significant occupational RF overexposure in an industrial setting most people never consider.

Researchers exposed dogs to UHF (ultra-high frequency) electric fields and measured how well their stomachs and intestines absorbed nutrients like amino acids. The study found that UHF exposure increased the absorption of amino acids in both the stomach and intestines compared to control conditions.

Researchers exposed isolated rat eye lenses to different temperatures to determine whether microwave-induced cataracts result from electromagnetic radiation or simple heating. They found that moderate temperature increases (39-41°C for one hour) caused cataracts similar to those seen in microwave studies, while very high temperatures (60-65°C) actually preserved lens clarity through a 'fixing' process.

Researchers used mathematical models to calculate how electromagnetic radiation penetrates and deposits energy in human heads, comparing adult and infant absorption patterns. They tested different head shapes (spheres, prolate spheroids, and ellipsoids) and found ellipsoidal models most accurately predicted power absorption. The study revealed that infants may absorb electromagnetic energy differently than adults due to their smaller head size.
