I don't think it was kept secret to diminish embarrassment or save face. The impact on satellites was an outcome of the test. It was part of the weapon's overall effectiveness. How well your weapons work on specific targets, even those outside the test area, is exactly the type of information you try to keep out of enemy hands.
But the UK and US have been allies for a very long time...
They didn't trust each other, with good reason. See https://en.wikipedia.org/wiki/Cambridge_Spy_Ring
You say that, but now that this is out it's only a matter of time before the bad guys realize they can stop using their nukes for leveling cities and repurpose them for disrupting HBO.
The sats for HBO are geostationary. Hitting them with nukes is a far cry from disrupting those in low orbits. You would need a much bigger rocket and significantly better aim (GST=35000km vs. LEO=150km).
Except not, because satellites are now hardened against this kind of radiation as a side effect of hardening against cosmic rays, etc.

If I recall correctly, there were a couple of people (I don't remember if they were astronauts or cosmonauts) in orbit at the time of Starfish Prime, whose space capsule passed through the radiation belt on its orbit. The space agency in question was pretty nervous about them getting fried as well, and was kind of upset they weren't informed ahead of time.
I doubt it. The vanallen belts were predicted long ahead of time and were confirmed during the very first sat missions (explorer 1). They were known not to be dangerous, at least not in comparison to riding a rocket. The amount of dangerous radiation penetrating any spacecraft would be minimal in comparison to that constantly funneled into the belt from space.
The vanallen belts are often mentioned by moon hoax people to suggest that manned spaceflight is impossible. Mr Van Allan has been interviewed several times to dispute this assertion.

As far as I understand the issue, the Van Allen belts themselves were not the problem, but the high energy electrons released by the thermonuclear explosion, which got caught in the belt. (Apparently the amount of high energy particles released during a solar mass ejection far exceeds that released by any of the nuclear weapons set off during Operation Fishbowl, but I guess people knew a lot less about SMEs back then.)
The only reference I can find right now is the Wikipedia article on "High altitude nuclear explosion", which says: "The radiation dose rate was at least 60 rads/day at four months after Starfish for a well-shielded satellite or manned capsule in a polar circular earth orbit, which caused NASA concern with regard to its manned space exploration programs."
Which sounds quite a bit less dramatic than I remembered.

I don't think there were any. Starfish Prime was on July 9th, 1962, with Mercury-Atlas 7 launching on May 24, 1962 and lasting 4 hours followed by Vostok 3 launching August 11th, same year. Take a look at:

You are right. Looks like my memory is not what it used to be.
Many good reasons for protect space from weaponization by treaty, too bad the article doesn't raise this issue better.
Is this the real life event that led to Goldeneye?
Another example of Classification used to censor something that poses no security risk, but holds huge reputation risk.
