Study of the Impact of Past Extreme Solar Events on the Modern Air Traffic
Space Weather, 2021 The ancient solar energetic particle (SEP) events of 774/775 CE and 993/994 CE were characterized thanks to radionuclide productions stored in environmental archives as ice cores or tree rings.

Temporal trends in satellite-derived erythemal UVB and implications for ambient sun exposure assessment [PDF]
, 2017 Ultraviolet radiation (UVR) has been associated with various health outcomes, including skin cancers, vitamin D insufficiency, and multiple sclerosis. Measurement of UVR has been difficult, traditionally relying on subject recall.

Ambient dose equivalent rate constant for several radioactive nuclides.
RADIOISOTOPES, 1988 Ambient dose equivalent rate constant (which is the quotient of l2H* (10) by A, where H* (10) is ambient dose equivalent rate at 10 mm depth due to photons at a distance l from a point source of the nuclide having an activity A) is calculated for 50 nuclides. The limitation of the validity of the quantity is also discussed.
