Gray versus grey

Outside the US, grey is the preferred spelling and gray is rarely seen, whereas the situation in the US is the exact converse.

However the spelling of the SI unit of absorbed dose is gray (named after the British physicist Louis Gray). Unfortunately our translation module does not understand context and therefore would autotranslate all instances of gray to grey, even articles with specific absorbed doses mentioned, resulting in nonsensical statements e.g. 3 milligrey etc.

Originally Radiopaedia preferentially used British English spellings, therefore we have chosen to use the spelling 'grey' across the site and not vary it with user preference.
