Current dose rate in Dülmen
The measurement takes place at our site in Dülmen
with a highly sensitive NaI scintillation detector, similar to our Scinto-system.The measured local dose rate is made up of the level of natural radioactivity in soils and the intensity of cosmic radiation.
By derivatives of the naturally occurring radioactive noble gas radon-222, which are washed out by rain and deposited on the ground, it can lead to elevated levels. It's products decay within a few hours. Thus, the typical value is re-established.
The highly sensitive detector for measuring the actual dose rate on our site is in the direct vicinity of a busy railway line. In some cases, e.g. radioactive transports by rail, it can lead to short-term increases of the current dose rate.
