Mary23 Posted December 6, 2015 Share Posted December 6, 2015 Which are the main radioactive elements around us? Link to comment Share on other sites More sharing options...
fiveworlds Posted December 6, 2015 Share Posted December 6, 2015 (edited) It depends on where you are. Here radioactive elements aka (uranium is plentiful here) form radon gas which is dense and therefore tends to accumulate in valleys that's why I live atop a big hill.

swansont Posted December 6, 2015 Share Posted December 6, 2015 There are two radioactive isotopes that are inside you. But people shouldn't just be giving out answers. What have you done so far to answer this? Link to comment Share on other sites More sharing options...
John Cuthber Posted December 6, 2015 Share Posted December 6, 2015 There are two radioactive isotopes that are inside you. But people shouldn't just be giving out answers. What have you done so far to answer this? There are more than 2. Also, if Fiveworlds thinks that dense gases accumulate in valleys to any meaningful extent, how does he explain that the people in these valleys don't die from CO2 poisoning. Perhaps he missed science 101; the properties of gases. http://www.bbc.co.uk/bitesize/ks3/science/chemical_material_behaviour/particle_model/revision/4/ Property of gases : They flow and completely fill their container.

swansont Posted December 6, 2015 Share Posted December 6, 2015 Fair enough. Two prominent ones. Link to comment Share on other sites More sharing options...
