Radon was discovered in 1900 and is the heaviest of all the known gases. The radiation it gives off kills cancer cells so it has been used as a cancer treatment in the past. It also used to be inside glow in the dark paints.
Radon is radioactive, which means it can give off harmful rays and can be dangerous when inhaled as it damages the inside of our lungs. Areas at risk from radon are tested regularly, and if a building is found to have high levels of radon a ventilator can be used to bring in more fresh air and get rid of it.
This is a general science zone with five scientists working in five different areas. There is one scientists who studies how genes make us who we are, one who is working out how hot it will get in the next 50 years and one who is a doctor researching medicine for children. One scientist uses x-ray cells to kill cancer and another is researching how our skin renews itself every two weeks.
