Is 3He:4He Ratio Redundant in Scientific Writing?

[matthyaouw]

"A high 3He:4He ratio signifies..."
I'm thinking that since the colon between the isotopes shows that it is a ratio already, using the word 'ratio' afterwards is a bit like writing PIN number. Is it acceptable to write it like this or should i get rid of the word 'ratio'?

To a mathematician, the word "ratio" might seem redundant, but the phrase scans better with the word included, IMO.

Ya I think the word ratio belongs.

I've always taken the colon in such applications to represent the word 'to', since that's the way it's spoken. In that case, the inclusion of the word 'ratio' is correct.

Or you could write it like this to avoid the redundancy but still keep it clear:

"A high ratio 3He:4He signifies..."

I would prefer in a previous sentence to say once that ³He:⁴He is a ratio and not need to be redundant.
