Page 3: Important Hint
The Thoron-Scout offers two calculation modes for the Radon concentration, one (Slow) includes both, Po-218 and Po-214 decays and the other one includes Po-218 only (Fast). -
Page 4: Operating The Instrument
Due to its small dimensions and little weight, the Thoron-Scout can be shipped by mail to the place of interest/measurement without any additional man-power required for installation or start-up of an analysis –... -
Page 5: Power Supply
Close the battery slot by screwing clockwise for 45° . Ensure a tight sealing of the cover. The Thoron-Scout offers an external DC input to supply the instrument by an AC/DC mains power adapter. -
Page 6: Carrying Out A Measurement
SARAD GmbH Thoron-Scout The remaining capacity is 15 ... 25% depending on the chemistry of the used cells. After pressing the Toggle button display presents measurement results as usually. If longer measurements are planned, the batteries should be replaced before to avoid unexpected measurement break. -
Page 7: Adjustment Of The Sampling Interval
SARAD GmbH Thoron-Scout The readings of the additional sensors are shown at the third page. Those values represent the average derived from all “one minute shots” of the whole integration interval. Ambient 12:20 21.5°C 987mbar 46%rH 12.3V TSC-00256 The next page shows the average values of the Radon and Thoron concentration from the very begin of the actual measurement series. -
Page 8: Pump
GmbH Thoron-Scout Pump There is no pump in the Thoron-Scout. The air exchange depends on diffusion process only. Alarm If the measured Thoron or Radon concentration exceeds the programmable alarm limit, the buzzer will sound shortly each second. The alert has to be acknowledged by pressing the push button. -
Page 9: Statistical Error (For Non-Mathematicians)
SARAD GmbH Thoron-Scout Statistical Error (for non-mathematicians) The radioactive decay is a statistical process. That means, even if the Radon concentration is constant over the time, the number of decays N counted within several intervals of the same period will be different. N will vary around the mean value of all considered intervals. -
Page 10: Is An Observed Concentration Change Statistical Significant Or Not
SARAD GmbH Thoron-Scout T(slow) = N / (C * S) = 100 cts / (0.2 kBq/m³ * 8 cts/(min*kBq/m³) = 62.5 min. That looks pretty but makes no sense because of the longer response time. So we will set the interval to 120 Minutes and ask for the statistical error in this case: N(slow) = C * T * S = 0.2 kBq/m³... - Page 11 SARAD GmbH Thoron-Scout intervals have to be averaged to get a usable result. This procedure is nothing else than to create an integration interval long enough to meet the Detection limit for the applied Radon concentration. To avoid zero readings, set the integration interval with respect to the lowest expected concentration level during measurement.
