SMART RADON MONITOR (SRM)

  Smart Radon Monitor (SRM)


The Smart Radon Monitor (SRM) is a technologically advanced real time, portable, radon monitor, designed for multiple applications in radon studies. Radon measurements are based on detection of alpha emitted from radon and its decay products formed in a scintillation cell. An Indigenous smart algorithm has been implemented in the micro-processor, which automatically compensates the background counts due to residual decay products of radon and thus able to measure radon concentrations in a continuous fashion.


The SRM is advantageous for

  • High radon sensitivity (1.2 cph/Bqm-3) despite low detector volume (153 cm3)
  • Wide measurement range of 5 Bq m-3 to 50 MBq m-3
  • Instrument sensitivity is free from the influence of environmental parameters like humidity and trace gas concentration
  • Flow and diffusion mode sampling
  • Thoron cut off by pin-hole technology
  • Programmable and independent sampling time and counting cycle time
  • Continuous unattended operation
  • Low operation and maintenance cost
  • Battery backup, compact and portable

The SRM is useful for continuous radon monitoring in air, water and soil. It may be used for measurement of radon emission (Surface/ Mass Exhalation) from various sources such as building materials, soil, rocks, coal, fly-ash, Uranium tailings etc. The SRM finds wide applications in nuclear sectors such as network based radon monitoring inside uranium mine, soil gas radon measurement for uranium exploration studies and base line survey for upcoming nuclear facilities. The monitor also finds application in public domain such as radon survey in houses, caves, seismic sites etc. It can be also used for calibration of radon active or passive detector system
