  1. TRACERLAB TRACERLAB offers a wide range of development, engineering and production of instruments, such as sampling-, sample preparation- and measuring systems, mainly to be used Natural Radiation, the Determination of Radon, Thoron and it‘s Progenies in the field of the Environmental- and Radiation Protection, including the instruments for the determination of natural radiation, Radon/Thoron and its Progenies, in the air, in the soil or in water.

  3. TRACERLAB Natural Radiation, the Determination of Radon, Thoron and it‘s Progenies ERS/RM-1000/250 Small Size and light weight Radon / Thoron Gas Monitor The ERS/RM-1000/250 is an active and direct reading Electrostatic Radon/Thoron Gas-Monitor, has a counting-chamber of 250 ml volume and is made for the determination of the Radon/Thoron-Gas Concentration in the air, or from the soil. The ERS/RM-1000/250 is a self contained instrument with all elements of an intelligent data collection with an alpha- spectroscopy-system. The standard version of the ERS/RM- 1000/250 has a 4-line LCD and the advanced version of ERS/RM-1000/250 has a Panel-TPC for the communication, ERS/RM-1000/250 evaluation of results and data-storage operation by diffusion-mode, or by pumping-mode Page - 3 -

  4. TRACERLAB Natural Radiation, the Determination of Radon, Thoron and it‘s Progenies ERS/RM-1000/250 - Radon / Thoron Gas Monitor Method of operation - Facts and Definitions The ERS/RM-1000/250 is an active and direct reading Radon/Thoron Gas-Monitor. It is operating as an Electrostatic-Radon-Sampler with a metallic hemisphere / counting-chamber of 250 ml volume and a positive High-Voltage of 3 kV connected to the metallic hemisphere. An Alpha-Sensitive Detector (Canberra PIPS-Detector) is built-in isolated on negative potential in the counting-chamber. Radon containing ambient air is entering the counting chamber by using the diffusion-mode through a sintermetal-air-inlet-filter with an active diameter of 70 mm. The other method of operation is by using the pumping mode. Radon containing ambient air, or soil-gas is sucked by the internal air-suction pump with an airflow-rate of appr. 120 l/h through an air-inlet filter into the counting chamber. The intelligent data collection with an alpha-spectroscopy-system, MCA with 256 channels, ADC, Pre- and Main-Amplifier is made for the collection of Po-218 for the determination of Radon and Po-216 for the determination of Thoron. Operational dimensions and weight: 325 x 255mm, x 135 mm high, appr. 8 Kg Electric power supply: Li-Ion-Battery, 14,4 V / 8,7 Ah, incl. charger. Runtime without AC-line connection to the charger: > 12 h Page - 4 -

  5. TRACERLAB Natural Radiation, the Determination of Radon, Thoron and it‘s Progenies ERS-2-S Radon / Thoron Gas Monitor The ERS-2-S is an active and direct reading Electrostatic Radon/Thoron Gas-Monitor, has a counting-chamber of 2.5 l volume and is made for the determination of the Radon/Thoron-Gas Concentration in the air, from the soil or from materials, e.g. for the determination of the Exhalation-Rate by using the special application-software. The ERS-2-S is a self contained instrument with all elements of an intelligent data collection with an alpha- spectroscopy-system. The standard version of the ERS-2-S has a 4-line LCD and the advanced version of ERS-2-S has a Panel-TPC for the ERS-2-S, advanced version with the Panel-TPC communication, evaluation of results and operation by diffusion-mode, or by pumping-mode data-storage.

  7. TRACERLAB Natural Radiation, the Determination of Radon, Thoron and it‘s Progenies ERS-2-S - Radon / Thoron Gas Monitor Method of operation - Facts and Definitions The ERS-2-S is an active and direct reading Radon/Thoron Gas-Monitor. It is operating as an Electrostatic-Radon-Sampler with a metallic hemisphere / counting-chamber of 2,5 l volume and a positive High-Voltage of 4 kV connected to the metallic hemisphere. An Alpha-Sensitive Detector (Canberra PIPS-Detector) is built-in isolated on negative potential in the counting-chamber. Radon containing ambient air is entering the counting chamber by using the diffusion-mode through a sintermetal-air-inlet-filter with an active diameter of 180 mm, or the ERS-2-S is placed on a material, to be examinated for the determination of the Exhalation-Rate. The other method of operation is by using the pumping mode. Radon containing ambient air, or soil-gas is sucked by the internal air-suction pump with an airflow-rate of appr. 120 l/h through an air-inlet filter into the counting chamber. The intelligent data collection with an alpha-spectroscopy-system, MCA with 256 channels, ADC, Pre- and Main-Amplifier is made for the collection of Po-218 for the determination of Radon and Po-216 for the determination of Thoron.
