A still better title would be "Radioactive spikes from nuclear plants could increase the likelihood of childhood leukaemia but there's no real evidence for it" However, that's not going to sell a lot of newspapers.
There does seem to be real evidence for it; but it's not quite the smoking gun yet.

Biologically, strontium behaves quite a lot like calcium- it is certainly concentrated in the bones. However, it doesn't normally get into the air so it can't be even part of the "spikes" which this thread is about. Caesium behaves rather like potassium and thus has a fairly short half life in the body. It too has little or nothing to do with this thread.
So, we have the inert gases - which they measured, but which are exhaled almost immediately so it's not clear how they could have much effect and we have things like strontium which would have an effect, but aren't released in these spikes . We also have thing like iodine which are likely to be released as a gas and have reasonably long biological half lives- but they didn't measure them. And we have a measurement that's made where nobody is actually exposed to it. Which when you look at the typical dilution produced by a chimney (remember, that's the point of a chimney) is probably rather hard to distinguish from background.
Then there's the plausible alternative explanation- for which there is evidence.
