Coconut water has several uses that are beneficial to humans, mainly because of its nutritional and medicinal properties. In this 2021 article from Natural Science, researchers from Tennessee State University collected coconut water samples from fresh mature coconuts and from packaged processed coconut water to measure their radon concentrations. The results were used to estimate the annual effective radiation dose to the general adult population from ingestion of coconut water. How can you not be curious? Click here

Risk perception is a complex psychological process subject to numerous unconscious, cognitive, and emotional biases that influence how we process radon information. These biases act to minimize our sense of risk. Given these challenges, it is not surprising that radon threats fail to promote appropriate precautionary behavior. Even where there is awareness of radon, apathy rather than a sense of urgency tends to be reported. To learn more, click here:Radon Risk and Remediation: A Psychological Perspective
Did You Know?
If soil gas contains lots of radon, it will usually contain significant amounts of thoron as well. When gas leaves the soil, both the radon and thoron start to decay. Thoron however has a half-life of less than a minute, so soil gas which has been out of the soil more than a few minutes will have lost almost all its thoron. Therefore, because of its short half-life, thoron will be found only close to the radon entry point.
The RAD7 is capable of making a direct and specific measurement of thoron. The first daughter of thoron, polonium 216, has a half-life of just 150 msec. So the response of the RAD7 to thoron is virtually instantaneous – all that is required is to get the thoron into the measurement chamber, which takes maybe 30 seconds. So sniffing for thoron has two big advantages over other techniques to locate radon entry points. One is that the thoron is localized to the radon entry points. The second is that the RAD7 response is instantaneous – you see it immediately when you sample close to the entry point.
DURRIDGE Tip
The RAD7's TEST LOCK command activates a security feature to prevent people from tampering with the instrument while it is in use. While the RAD7 is locked, active measurements will continue uninterrupted, but the buttons on the keypad become unresponsive.
If you select >Test Lock and push [ENTER], the keypad will lock and the LCD display will just show: DURRIDGE RAD7 No-one will be able to unlock the keypad, unless they know the secret.
To unlock the keypad, hold the [ENTER] and both arrow keys down for 3 - 4 seconds, or until the unit beeps, then release the three keys and push [MENU] immediately.
RAD7 Radon Detector – Real-time Continuous Radon Monitor with Spectral Analysis – is our new purchase. This equipment will be used for 222Rn measurements to trace submarine groundwater discharge. The RAD7’s technology (electrostatic precipitation followed by high-resolution alpha spectrometry) is the only one that gives clear separation between the various radon progeny species (‘species identification’).
