  • Best sensitivity to size ratio
  • Belongs to the CSP family
  • Calibration via PC software
  • Extends existing CSP instrument’s dose-rates to background measurement
  • Plug and play
  • Low power consumption
  • ICRP60 compliant

Description

The SVLD probe for measurement of Very Low Dose equivalent rate is designed to be used with CSP™ meters such as Radiagem™, MIP 10 Digital, AVIOR® or Colibri®. 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 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’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 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 is part of CANBERRA’s innovative 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.

Benefits

  • Offers maximum sensitivity in a compact size
  • Quickly and accurately measures Very Low Dose equivalent rate
  • Extends the application range of existing CSP instruments
  • Reduces Total Cost of Ownership
  • Does not saturate before significant dose equivalent rate (1 mSv/h – 100 mrem/h)
