21. Exposure to ionising radiation can induce cancer in almost every organ in the body. 22. This ionising radiation may cause damage to materials within both the tether and climbers. 23. The illness caused by exposure to ionising radiation is called " radiation sickness ". 24. It is visible as the knot of filaments growing green from ionised oxygen emission. 25. Cell phone and wireless device radiation is too low in frequency to be ionising . 26. In 1915 proof was given that it was actually ionised helium-helium II. 27. In solution the fluorosulfate anion is completely ionised . 28. They are all prone to hydrolysis, and ionise to give rise to polyhalogen ions. 29. This ionised layer excludes the solar magnetic field, giving Venus a distinct magnetic environment. 30. Doubly ionised acetylene HCCH 2 + reacts inefficiently with argon to yield HCCAr 2 +.
