The SVLD probe for measurement of Very Low Dose equivalent rate is designed to be used with CSP instruments such as Radiagem™ meter, MIP 10 Digital™ meter, Avior or Colibri units. Its CsI(Tl) detector with specific energy compensation (patent pending) makes it an ideal tool for differentiating background dose-rate starting from 10 nSv/h. Most portable dose equivalent rate instruments only estimate the background radiation exposure. The SVLD device is designed to quickly and accurately measure very low dose equivalent rates near background using a lightweight CSP compatible probe. Unlike heavy and very large probes, the SVLD probe's small size can be carried easily by a user in the field. The SVLD probe not only measures very low dose-rates but does not saturate up to 1 mSv/h (100 mR/h) covering most daily Health Physics duties.
The SVLD unit is the perfect choice for dose-rate control at radiation area boundaries and daily dose-rate measurements outside of radiation areas like inter-building paths in public areas. It is also very useful for interdiction situations in crowded areas and can be deployed at gates or pathways – its small size and wireless capability, when coupled with a CSP-COM module, make it the perfect low visibility monitoring device.
Industry and medical users can quickly confirm presence of radioactive sources (medical radionuclides, waste, NORM) and easily set a safety perimeter based on accurate dose-rate measurements.
The SVLD probe is part of the innovative CANBERRA™ SMART Probe (CSP) family. It includes all key components of hardware circuitry (high voltage power supply, amplifier, discriminator, etc.) Additionally, the intelligence associated with controlling those components is located inside the probe. This includes control and storage of key parameters, settings, calibrations, probe ID, alarm settings (10 values for each unit to display with default setting), etc. Thus the probe is a fully integrated subsystem taking and transmitting the measurement to the instrument, which is used for display.
