In plain terms
The summary report says the beam is strongest at the middle of the receiving site, at about 240 watts per square metre, and argues that this makes it safe because sunlight is stronger.
The claim as recorded
The Frazer-Nash executive summary states the maximum beam intensity at the centre of the rectenna is limited to around 240 W/m2, and concludes from that comparison alone that the system is inherently safe for life on earth.
Scope and limits
The word "Thus" carries the entire safety argument, and it rests on an analogy to solar flux rather than on any radio-frequency exposure standard. This claim may be cited as evidence of what the study asserts. It may NOT be cited as evidence that the system is safe.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
Quoted verbatim, p17: "The maximum beam intensity at the centre of the rectenna is limited to around 240W/m2, or about a quarter of the intensity of the sun at the equator. Thus the system is inherently safe for life on earth."
