Science812 (talk) 15:06, 5 May 2022 (UTC)In the first paragraph, I recommend the following additions and corrections:

(Radiation) skyshine describes the intensity of ionizing radiation in the atmosphere around a vault of an industry nuclear facility or a radiation oncology medical facility. Such radiation, generally measured in terms of exposure-rate or dose-rate, are not induced in the surroundings directly, but rather indirectly. Skyshine is created through reflection and scattering off of the surrounding atmosphere, back to earth's surface. This effect can happen when the shielding barrier for a nuclear facility around the source of radiation is open at the top [3,4]. It can also happen when the shielding in the vault room of a medical accelerator is not sufficient to reduce the intensity of the primary incident beam down to a very low level [2]. For example, a member of the public may be positioned outside of such a room or vault in a nearby parking lot. For for a nuclear facility the room which is open at the top, or for a radiation oncology facility with limited shielding in the vault ceiling, then even if the radiation is directed straight up into the atmosphere, there can still be a significant amount of radiation measured at the position of the member of the public standing on the ground in the nearby parking lot. It has been shown that this downward intensity of skyshine radiation is heavily dependent on the shape of the beam. Regardless of whether the upward incident beam is shaped like a circle, square or rectangle, specific calculation formalism has been described [9,10].

The order of the references could be re-organized with the inclusion of these new citations at #9 and #10, or you could just add them onto the end. Here they are for your convenience. They are available to the public if needed.
