Do you means an info for each radio option in a radio group? It was not implemented. Maybe because it's still not implemented for all OS. (link)
You can set one for the entire group. You just need to add the {info,String} to the flags property in their definition.

Code:
{hradio,[
{?__(29,"Spotlight"),spotlight},
{?__(30,"IES"),spot_ies}
],Type,[key(type), {hook,Hook_Show}, {info, "bla,bla,bla"}]},
