DESCRIPTIONS
Applications
RD200 is a real time smart radon detector for home owner
which has the high sensitivity 0.5cpm/pCi/l, about 20~30
times more than conventional radon detector by FTLAB’s high
stable circuit technology.
Its first reliable data out time is below 60min from
measurement start. Also the accuracy is <10% at 10pCi/l.
(The accuracy and precision spec were tested by the KTL(Korea
Testing Laboratory) administrated by KOREAN government)
RD200M is a radon sensing module for OEM supply.
RD200= RD200M+ display+ logger+ Bluetooth+ etc
* NET certification from Republic of South Korea (2015.12)

Theory of Operations
Radon Measurement by pulsed ion chamber
Fig1. Pulsed Ion Chamber theory
Fig 2. L75 x D60, 200cc class ion chamber
Figure 3. Improved detecting signal by FTLAB’s circuit technology
α-particle that are generated during the radioactive decay of
radon and radon progeny create the thousand of ± charge
particles by collision with air in Figure 1. These electric
charges signal is usually very weak and noisy, so it is difficult
to amplify the signal using a circuit having a high input
impedance. RD200 detects effectively these secondary
charges using the built-in 200cc class pulsed ionization
chamber in Figure 2 and a special amplifier circuit developed
by FTLAB’s own technology. The improved detection signal is
shown in Figure 3. Thus, from the statistical method based
on frequency, pulse counts and interval of these alpha decay,
it can be measured the average radon concentrations indoor.

Compensation technic in RD200
Figure 4. Compensation by MCU using waveform analysis & sensor data
RD200 has been applied to a special signal waveform analysis technology. Based on the very stable
signal waveform, it can be introduced a algorithm to distinguish normal alpha signal waveform and
the noise waveform in internal MCU.
Also it was overcome the shortcomings of the ion-chamber system by utilizing a various smart sensor.

Comparison of RD200 with other devices
RD200 is the first real time Radon detector in the low price market . The performance
of RD200, sensitivity or response time is closely up to the inspection/research devices.
However the Price of RD200 is nearly same with other conventional cheap devices on
public domain.
No longer need to wait a long time to find the indoor radon concentration. No longer
need to buy a expensive device to check the accurate value. You can just enjoy the
excellence performance of RD200 as a Best price.
