5 Nov 2009, 5:34 PM  | chemical properties of radioisotopes? Help please You can hide this advertisement by registering. This question was from the 2007 CSSA trial: explain a use of a medical radioisotope in terms of ONE of its chemical properties.It's probably a simple question because its 1 mark but I have no idea as to what chemical properties of radioisotopes entails because I've only ever studied their nuclear properties. Thanks in advance. |

19 Nov 2009, 3:59 PM | Re: chemical properties of radioisotopes? Help please see that word 'chemical'? They r gonna delete that word in the syllabus when the new one comes out. Just say something basic. e.g. Technetium - 99m is used for medical purposes (in diagnostics and treatments of diseases) because it has a short half life of 6 hrs. This makes it appropriate to use, as this property will ensure as less radiation exposure to the patient as possible. |

Yesterday, 2:25 PM  | Re: chemical properties of radioisotopes? Help please We went through this question at the TSFX lectures with a senior marker who marked it. She said they accepted nuclear properties instead of chemical properties but we only learn nuclear properties XD

5 Nov 2009, 5:34 PM | Re: chemical properties of radioisotopes? Help please lol half life is a nuclear property...haha if they accepted nuclear properties that means that no one came up with any chemical ones. apparently a chemical property of Tc-99m is its ability to be chemically combined with tin which then attaches itself to red blood cells. Thus abnormalities in the circulatory system can be detected. |
