Low confidence
The evidence behind this statement is thin, indirect or second-hand. Read it as a lead to check, not as a settled finding.
In plain terms
Two hours a day at about 100 W/m2 warmed rats by about a degree and shifted blood counts for a while, without lasting harm on the tests used; 500 W/m2 overheated them quickly.
The claim as recorded
A 1973 journal paper reports that rats exposed unrestrained to 2400 MHz CW at 10 mW/cm2 (100 W/m2) for 2 hours a day for 10, 20 or 30 days (10 rats per group) showed a rectal temperature rise of about 1 deg C in the first 30 minutes, then stable; erythrocyte counts rising throughout; other blood elements rising up to 20 days then tending back to baseline by 30 days; no eye changes; and no change in survival time at a simulated 11,500 m altitude. A group exposed once at 50 mW/cm2 for 20 minutes rose about 6 deg C and then survived significantly less long at simulated altitude; continued exposure at 50 mW/cm2 caused convulsions and death.
Evidence behind this: T1, a refereed journal paper; it permits "the paper reports Y". 10 rats per group.
Scope and limits
ANIMAL, NOT HUMAN. n = 10; blood results given as trends in figures without stated significance. Near or far field and probe calibration not stated; the source is a diathermy generator. 2 h x 30 days = 60 h (my arithmetic). Frequency 2400 MHz, not 2450.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
PDF p.2: groups, schedule, Meditron 200 generator at 2400 MHz, Medik-Po 1 detector (paraphrase). PDF p.3: temperature about 1 deg C in 30 min at 10 mW/cm2; blood changes by day (paraphrase). PDF p.4: survival at altitude; 50 mW/cm2 effects (paraphrase). PDF p.5: no cataracts at 10 mW/cm2 (paraphrase).
Basis: mW/cm2 incident (Medik-Po 1 detector), 2400 MHz CW; 2 h/day for 10, 20 or 30 days
