If you are desperate then but that down, because the radiation emitted are gamma rays or whatever..which passes through the skin.. ALSO the radiation damage to the body is minimal since Tc is weakkradiation is harmful, especially for workers in hospitals who are dealing with it all the time.
because its not a good reason.. in my opinion.. considering that the properties of it is that the radiation passes through humans which doesnt do any damage to the person.. so it wouldnt effect the medical practitioner and also the Tc is injected in small amounts.. even if you handle it many times... it would have little effect on the person..that's your first reason. why would you not put that down?
you dont need to know half the stuff that you said for the hsc..ANSTO question booklet for sure :L its produced as Mo which has a half life of 66 i fink and den it is stored in the capsule and transported to the hospitol where it becomes Tc (the capsule thingy is lead and some coating to stop the radiation becomming x-rays) den at the hospitol staff shoved in some substance (starts with s and contains a salt or sugar) and it is collected using a vacumm needle which sucks out the Tc and the added substance and injected in humans to be scanned
LOL sorry for the rough answer but its some help
They wont go so specific.. the dot point is3 mark question on safety issues associated with Tc-99m. What three are you going to use? (plus minimisation factors)
They would not go specifically asking for Tc.... read the dotpoint.. radioactive isotopes in industry and medicine.. It does NOT say Tc.. Show me a question in past HSC papers where it would ask to name more than one problems dealing with radioisotopes then I would say that I'm wrong.how is that not a specific dot point?!
