If it did, then what kind? Or if it didn't, was it because the flight didn't last for too long? (7 days or so, from Earth to Moon and back.)

    $\begingroup$ A combination of a radiation measurements were taken via probes to assess the risk, short duration of the journey & weight restrictions for the space craft. The skin on the lunar module was so thin it could have been easily punctured with a pencil, if I recall correctly a statement made by Buzz Aldrin in one of his books. While traveling to & from the Moon & while on the Moon, most astronauts reported seeing strange flashes of light. This was later attributed to cosmic radiation hitting the retinas of the astronauts eyes. $\endgroup$

    $\begingroup$ The heat shield of the Command module had a shielding against solar radiation. The heat shield has several outer coverings: a pore seal, a moisture barrier (a white reflective coating), and a silver Mylar thermal coating that looks like aluminum foil. The silver mylar coating was a shield against IR, visible light and invisible UV radiation as well as low energy alpha rays. $\endgroup$

  • $\begingroup$ I agree that it is a duplicate of the question specified by @Hobbes; however, note that the answer is in the non-accepted answer of that question. $\endgroup$
