In plain terms
One hive lived for four weeks, a full brood cycle, under the beam strength expected at the edge of a receiving station, and behaved like the identical hive next door with the beam off.
The claim as recorded
A whole honey-bee colony kept 28 days in an anechoic chamber "at an exposure level (1 mw/cm2) anticipated near the edge of a rectenna", a period that "exceeds that required for the completion of one cycle of brood", held its brood-nest temperature and humidity in the normal range "indicating no effects caused by the microwave treatment", reared eggs, larvae and capped brood across its 3,895 cells in step with the sham colony's 3,855 except for timing differences the authors attribute to the queens and to late-summer cannibalism, so that "The variation between the brood rearing activities of the two colonies was within the normal range of variation experienced in nature", and kept its weight between about 2,200 and 2,400 g like the sham.
Evidence behind this: T3-one colony against one sham colony for 28 days; a demonstration, not a replicated experiment, and the report's own comparisons are descriptive.
Scope and limits
ONE COLONY AGAINST ONE, NO REPLICATION AND NO STATISTIC; the edge level only (1 mW/cm2 = 10 W/m2), not the 23 mW/cm2 centre. Late-summer timing, when brood rearing declines naturally, is the season stated.
What it assumes
One colony per arm is the design; the authors present the comparison descriptively.
Where it comes from
PDF 84 / printed 77: "at an exposure level (1 mw/cm2) anticipated near the edge of a rectenna. The exposure period (28 days) exceeds that required for the completion of one cycle of brood" (normalised). PDF 94 / printed 87, Fig. 5.5 (render reading): daily maximum and minimum brood-nest temperatures of both colonies in the low-to-mid 30s C against chamber ambient in the 20s, microwave and sham interleaved. PDF 95 / printed 88: "indicating no effects caused by the microwave treatment" (raw); "The total number of comb cells available in the 4 combs of each colony was 3,895 and 3,855" (normalised); "The variation between the brood rearing activities of the two colonies was within the normal range of variation experienced in nature" (normalised). PDF 103 / printed 96, Fig. 5.12 (render reading): colony weights between 2,200 and 2,400 g over four weeks, both curves. Recomputed: 3,895 - 3,855 = 40 cells, 1 per cent, so the comb bases were matched.
Basis: 1 mW/cm2 CW at 2.45 GHz for 28 days; brood-nest temperature in C; cells of eggs, larvae, capped brood, honey, pollen; colony weight in g
