Abstract

The hematological and blood-chemistry effects of chronic microwave radiation on unrestrained rhesus monkeys trained to expose their face and eyes to 9.3GHz microwave radiation at an average incident power density of 150 or 300mW/cm2 are reported. Only inconsistent transient effects were found. The lack of significant hematological effects, together with the lack of ocular or behavioral changes reported earlier, support the idea that microwave frequencies in the range of 10GHz may be safe to use for caloric supplement of hypothermic individuals and medical patients.

Main findings

In rhesus monkeys chronically exposed to 9.3 GHz microwave radiation at average incident power densities of 150 or 300 mW/cm2, only inconsistent transient hematological and blood-chemistry effects were reported. The abstract states a lack of significant hematological effects and references earlier reports of no ocular or behavioral changes.

Outcomes measured

hematological effects
blood-chemistry effects
ocular changes (reported earlier)
behavioral changes (reported earlier)

Limitations

Sample size not reported in the abstract.
Exposure duration details beyond 'chronic' are not provided.
Outcomes beyond hematology and blood chemistry are referenced as reported earlier rather than presented here.
