Learning about type of radiation in museum (6)
I believe the answer is:
louvre
'museum' is the definition.
(art museum in Paris)
'learning about type of radiation' is the wordplay.
'learning' becomes 'lore' (both can mean tradition or knowledge).
'about' means one lot of letters goes inside another.
'type of radiation' becomes 'uv' (I can't justify this - if you can you should give a lot more credence to this answer).
'lore' placed around 'uv' is 'LOUVRE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for louvre that I've seen before include "European museum" , "that's normally closed during the winter?" , "Great art museum-gallery in Paris" , "Parisian landmark - slat" , "Paris museum; type of window" .)
