Yes. Liquids are transparent to radiation. But it is an engineering consideration that they are opaque.

Refer introduction to heat transfer by incropera.

Well, Visible light is also an electromagnetic wave which can propagate through liquids. Then why liquid considered as opaque?

Opaque (means) : not able to be seen through; not transparent.
