Proton the particles in the solar wind are electrons and protons, in approximately equal numbers. Protons also have extrasolar origin from galactic cosmic rays, where they make up about 90% of the total particle flux. These protons often have higher energy than solar wind protons, and their intensity is far more uniform and less variable than protons coming from the Sun, the production of which is heavily affected by solar proton events such as coronal mass ejections. Research has been performed on the dose-rate effects of protons, as typically found in space travel, on human health. To be more specific, there
Sun Stream the Rowley Mile to the adjoining July course. Ridden by Wragg, she won by three lengths from Blue Smoke, with Mrs Feather a further two lengths back in third. Sun Stream's success gave Lord Derby a seventh win in the race as both owner and breeder, and was very popular with the unusually large crowd. A month later, Sun Stream returned to the July course on 8 June for the Oaks Stakes. Although the race was not run at Epsom Downs Racecourse it was given its traditional name: wartime runnings at Newmarket had been known as the "New Oaks". The
