The system is comprised of the radiameter FH 40 G with an integrated proportional counter tube and a FHZ 672-2 NBR scintillation probe. While driving, the high-sensitive scintillation probe recognizes even a minimum of artificial gamma radiation in the measurement range of nSv/h, in a wide area. The measured track of radioactivity is automatically shown on a digital map supported by GPS.
- Offers a high degree of mobility; also offers advantages in the reproducible sample geometry and comparability of measurements
- The multipurpose radiameter FH 40 G itself is able to determine the actual gamma dose rate
- Results can be stored in the internal memory of the survey meter
- With a measuring time of only five minutes, the detection limit is approximately 500Bq/kg for Cs-137
- Allows monitoring of limit values according to WHO intervention guidelines (e.g., fruits 7,000 Bq/kg; milk 4,500 Bq/kg; drinking water 7,000 Bq/kg)
- Utilized the patented NBR (Natural Background Rejection) technology to reduce false alarms
Compliance: The Radiameter FH 40 G has the German PTB approval as well as the German Fire-Brigade-Approval; proprietary NBR technology has also been approved by the TUV Hannover/Sachsen-Anhalt.
Applications in immediate in-situ measurements of alpha and beta contaminations:
- Filters and filter systems
- Smear tests
