High resolution Gamma spectrometry

Sample Changer Gamma Analyst:

• 1 integrated system DSA 2000/A CANBERRA 3106 (0-5 Kv)
• 1 CANBERRA detector BE 3830 – 5 Kv

Gamma spectrometer with a high purity Ge detector and an automatic sample changer (Gamma Analyst – CANBERRA)*

Four high purity Ge detectors:

• 3 of high energy (CANBERRA GC3019 – 5Kv; GC4018 – 3Kv; GC3518 – 3Kv)
• 1 of low energy (CANBERRA GL3825L – 4Kv)

The gamma detectors can be used for the measurement, identification and quantification of Natural Occurring Radioactive Materials (NORM) in different type of samples. 

Besides this, instrumental neutron activation analysis comparative method can be done with the determination of 30 chemical elements with high precision and accuracy. Prior to this, samples of diverse types (geologic, environmental, biological and cultural heritage) have to be irradiated in a nuclear reactor.
