The detection unit is installed in compact lead shielding on the stable platform. Lead shield is used to protect measuring sample from interactions with other samples, laboratory or natural background, which is very essential in case of acquiring spectrum of a sample with low activity.
The most suitable detection unit is used depending on application of the TRIO.
Every channel is equipped with specially designed shielding. Refer to the gallery to get introduced.
It is possible to change combinations of channels depending on the application in each particular case. For example, Gamma-Gamma-Alpha, Alpha-Gamma, Beta-Beta-Beta, etc. Same as extension of channels is possible in case application changes in time.
