About radiation

Gamma radiation (╬│ radiation) is an invisible electromagnetic radiation with higher energy than ultraviolet light and x-ray. Gamma rays, just as light and radio waves, are a form of electromagnetic radiation. They therefore consist of vibrating electric and magnetic fields. The difference between all these types of electromagnetic radiation is in the frequency of these vibrations, or in the energy or wavelengths that are coupled to the frequency.

The energy of gamma rays is so large that when they pass through a material, chemical bonds can break and electrons can be detached from atoms (ionisation). This can be both useful and dangerous.

If the human body is exposed to excessive amounts of gamma radiation, chemical bonds in the molecules of our cells will break down, causing the living tissues to be damaged. In places where gamma radiation is produced, for example in nuclear power plants, the necessary protective measures must therefore be taken.

Together with WISE International and RIVM, Waag developed GammaSense to enable citizens to measure radiation with open-source sensors in order to create a more detailed and complete data network, that allows for a quicker response in the case of emergencies.
