Opacities may also result as a cumulative effect of repeated subthreshold exposures. Intraocular temperature increases during irradiation, related to power density, but a particular critical temperature for opacity induction cannot be identified.

Researchers exposed Saccharomyces cerevisiae vegetative cells and ascospores to 2450 MHz microwaves using a hexane-cooled apparatus designed to separate thermal from non-thermal effects. At 40 watts without coolant flow, total loss of viability occurred after 30 seconds for vegetative cells and 40 seconds for spores, while suspension temperatures remained below 33°C.

Interlock testing requires at least two operable safety interlocks and the oven should turn off before leakage exceeds 5 mW/cm² during slow door opening. Closed-door leakage measurements use a standard water load of 275 ml in a 600 ml beaker and the probe is moved along the door crack at no faster than one inch per second. Ovens manufactured after October 6, 1971 must bear a DHEW certification label showing compliance with 42 CFR Part 78.

Nonthermal effects are classified as strong (above 10 mW/cm²) or weak (below thermal levels), and the review finds no evidence for weak nonthermal effects. The 10 mW/cm² exposure standard is based on thermal considerations and applies only to microwave frequencies where the human absorption cross-section is near unity; at lower frequencies the guide numbers can be relaxed by orders of magnitude.

The study exposed cat heads to 915 MHz microwave radiation and measured evoked tactile and auditory CNS responses. Changes in latency and/or amplitude occurred at a mean threshold of about 5 mW/cm2. Temperature rises were always associated with the changes. Variations in results were noted with different electrode compositions, suggesting possible artifacts.

Gamma radiation at 16 kilorads can sterilize most stored-grain insects, while 20 to 30 kilorads may be needed for all species, and the FDA has approved its use for wheat and wheat flour. Infrared heating of grain to 65°–70°C controls all developmental stages of stored-grain insects, but the treatment cost has prevented practical use.
