In plain terms
In 1980, by the US assessment's figures, the Soviet limit for the general public was two thousand times lower than the American 10 milliwatt guideline. The 1978 American design's fence line was set at a level that would have been legal in Canada or the United States and twenty times over the Soviet public limit the assessment gave.
The claim as recorded
As of August 1980 the DOE assessment records that the UK, France and West Germany held limits "essentially the same as the current ANSI guideline" of 10 mW/cm2; that Canada had revised to 1 mW/cm2 continuous nonoccupational (10 MHz-300 GHz) and, for 1-300 GHz occupational, 5 mW/cm2 for 8 hr/day, 10 mW/cm2 for 6 min or less and 25 mW/cm2 for 2.4 min or less; that Sweden had cut occupational levels about tenfold in 1976; and that the Soviet general-population limit was 5 uW/cm2 for 24-hr exposure with occupational levels from 10 uW/cm2 for a working day to 1 mW/cm2 for 20 min - so the 1978 Reference System's 1 mW/cm2 rectenna edge equalled Canada's public maximum and its 0.1 mW/cm2 exclusion boundary was 20 times the Soviet public limit.
Evidence behind this: T3-programme summary assessment; second-hand summaries of four national standards, none held.
Scope and limits
Second-hand summaries of four national standards, cited by the source to its own detailed volume (ref. 2 = SRC-086); none of the national instruments is held. The source's explanation of the Eastern levels ("philosophically based ... assumption that every effect produced by microwaves is potentially harmful", p.21 / 11) is the authors' characterisation.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
p.22 / 12, render read: "The maximum permissible nonoccupational level for continuous exposure is 1 mW/cm2, applicable to frequencies from 10 MHz to 300 GHz ... the new standard permits exposure to 5 mW/cm2 for a maximum of 8 hr/day, up to 10 mW/cm2 for 6 min or less, and up to 25 mW/cm2 for 2.4 min or less." "The Swedish standard ... was revised in 1976. Again, the new maximum occupational exposure levels are about ten times lower than they were." "In the Soviet Union, the maximum level for 24-hr exposure of the general population is 5 uW/cm2 ... from 10 uW/cm2 for a full working day to 1 mW/cm2 for 20 min of exposure." The source prints the micro sign; "u" is ASCII substitution. The last clause of the claim is arithmetic on CLM-0020's profile, not a statement in the source.
Basis: mW/cm2 and uW/cm2 by exposure duration
