Irradiation by a source does not make you radioactive

 

 

 

 

Objects, but also animals and people, do not become radioactive when they are exposed to alpha, beta or gamma radiation. They do not even have to become contaminated, even when touching te source. We show this by pouring clean water in to a radioactive glass (uranium glass). The water in the glass is exposed to radiation, but it does not become radioactive. We demonstrate this by pouring the water in a normal glass beaker and measure it. You could even drink the water. We do not do this, because we keep the safety rule never to eat or drink in laboratories!
 

The radioactivity in the uranium glassware is easy to measure, but it is not a very strong radioactive source. Because of this, there is no increased irradiation risk and no additional safety measures are necessary.
