@@Glencoe-Radvac hello can you maybe tell me what colin furzes radon results are because we'll over 3 months past and he dint even post a video about it and in his video no where are the Radon biscuits
As an environmental science and geological contamination graduate I am very interested in this and very appreciative of these videos with Colin Furze bringing the subject to the mass audience. Most people don't ever consider this stuff, but geological gases can be pretty hazardous if not lethal. A thing to note is that radon is heavier than air, so basements and cellars etc are particularly vulnerable. I will watch with interest to see the outcome.
It's funny. I bought my second home pretty cheap (less than $100k), because it has a Radon mitigation system (Real estate agent was telling me other potential buyers were turned off by it). People were passing it up, afraid or unaware. I snatched it up. I installed a couple detectors/readers, and in the last 2 years I get nothing showing. Meanwhile....they all probably bought other homes.....with Radon. Live and learn.... ;)
The house I live in New York has a radon system. It was put in before we moved in when I was young. Weird weird how the whole area is high radon. But only two houses have a system to deal with it.
Did the same thing here in Australia, but it turns out our radon levels are surprisingly low, despite our uranium mines. Didn't expect that! At least there's one thing here that isn't trying to kill us
It can migrate through the steel - this is the issue with hydrogen by the way. Like that they discuss mitigation. In the end, way better ventilation solves the problem. And that solves lots of other problems (air quality, heat recovery, co2 levels) too so personally I'd see a radon mitigation system as a plus for a home.
This is really making me more aware about Radon gas, and thumbs up on explaining the detectors. I'm curious what the North East of Lincolnshire is like for Radon.
Lincoln up to Scunthorpe is a very high risk area, east towards Louth is also the same. See for yourself here: www.ukradon.org/information/ukmaps Make sure you click the red button “show radon data”
The way how they talk about this 'gas', how it penetrates through everything, it's more like talking about 'radiation'. A normal gas, in whatever form, would not pass a layer of 30cm (1ft) of concrete. By this logic every person in this neighborhood should have their basement checked. I cross referenced this information with official Radon Gas research and the guy was correct that in the town where Colin lives (Stamford) you can see a whole belt of measured radon gas going between Birmingham and London, also straight through Stamford, where Colin lives.
@@robinlarge1630 There''s a UK radon map, I checked Buckinghamshire and it's a relatively safe area, and if I remember right the band of relatively low levels extends westwards into Bedfordshire.
These era houses don't really have basements, they're not all that common for most of the 20th century housing and later here in the UK. But even so, it can permeate from below even if you don't have a basement so yeah a bunch of these houses should be checked.
@@robinlarge1630 What I was trying to refer to was that common saying. I forgot what it was called. When you start learning a subject you don't know much about it. After a while you get to a point where you think you know everything about it. You continue learning and then find you actually know nothing about it still. I forgot the correct saying for this but its well known. It's a bell curve of knowledge as we all do it.
Growing up in a terraced house, we had some neighbours who had high levels, and some that didn’t, we didn’t luckily although it was a very high area as was all tested by some official body at the time (80s/90s)
How about a decent air handling unit outside bringing in fresh air with filters and a heater battery to temper the air? Creating that overpressure with clean air to displace any radon.
@@kylekelly1167A normal active radon mitigation system for say a basement uses a fan to create a low pressure under the basement slab to draw the radon gas out and vent it outside. This gives it a faster path out than penetrating into the basement, and the standard atmospheric pressure in the basement helps keep it out. With the tunnels and bunker Colin would have to cut through the steel and concrete to install exhaust fans like that, and normally there is a gravel bed under the slab that the gas can travel through to reach the exhaust. IIRC the concrete is poured directly on the earth for the bunker. So this may not work at all. What is being suggested is an overpressure ventilation system. Push more air into the bunker than escapes, which raises the pressure and pushes outward, reducing gas infiltration. The increased ventilation would also dilute the concentration of any radon that does enter the bunker. Given how all the tunnels and the bunker will eventually be connected, I'm not sure an overpressure system for the whole network will be practical. But just increasing the ventilation to exchange the air more often, with something like an energy recovery ventilation system, could keep radon concentrations low enough to be safe. He might want to seal of the garage from the rest of the system anyway, since cars are full of hydrocarbons that outgas. It might be best to ventilate the garage separately to keep all the VOCs and such controlled there and not permeating the whole system.
@@kylekelly1167You normally create a low pressure area under the foundation using a suction fan. This will keep the radon outside, and is quite effective.
Would be interesting to know if the readings from those CR39 based detectors can be influenced by X-ray scanners as they go through the postal system? Or is your lab able to discriminate between that and the Radon damage? Also is there a reason why your detectors don't have the typical filtered air holes to ensure the room air can easily pass in and the alpha decay can strike the detector?
They are also influenced by Thoron which can also give overly high readings,so basically not the most accurate way to determine an accurate result. When did Keith Lard stop wearing glasses?
Why 3 months? If there's levels it should be noticed in a week? You can do a year or multiple years too if you want all kind of weather and seasons to be taken into account.
The longer the test the better. Three months gives you an annual average radon level for the year. Radon levels fluctuate, so one week you could have high levels, one week they could be low. So depending on which week you tested, you could have a false positive or false negative result.
It's quite simple: you barely notice Radon radiation against the background noice. The collapse of a Radium atom (the atom one above the decay chain) happens at random and is minute. Thus, to identify the decay surplus over the natural noice, the longer the better. It is not an instant killer. A constant exposure to natural levels of Radon will not cause an acute radiation syndrome. However, areas with high Radon levels tend to have higher cancer levels. Particularly, people who execute their hobbies in basements are over proportionally affected.
I guess those detectors are detecting alpha particles (as that's the dangerous part of the Radon decay chain)? I've just signed up for the next free Radon tests here in Austria (there's a limited number that's given out twice a year, if I understood correctly). Should be getting them in July/August. I intend to set them up in the two rooms I work in most of the time (a basement workshop and ground level office). How far away from other radioactive sources do they have to be to not get false readings? Don't call the cops on me, but I got a vintage radioactive alarm clock (Radium painted digits) and radioactive tile pieces and plates (Uranium glazing). If the biscuits are only sensitive to alpha particles this shouldn't be a problem at all though, as alpha particles don't travel far and don't even get through paper. Btw. no worries, I had the radiation levels of the objects measured (not dangerous, unless you turn the things into dust) and I have them also marked for other people to be aware.
The amount of things that "could" cause cancer in 40 years down the road that a person interacts with every day, puts Radon really really low on the list honestly.
ok but ventilating would flush radon away...isn't it??? instead of having it piled up in the bunker.... the radon atom is way more heavy than nitrogen and oxygen so have a tendency to accumulate in the lower level of a room. The decay of it though, would be present in the whole room. Any physics dudes around???
Radon mixes thoroughly in the air. It doesn't sink to the floor. My house had levels of about 70 piC/l (2625 Bq/m3) and it was about the same reading in every room from the basement to the second floor. Opening every window and door in the house with fans in the windows on a windy day would clear it out in a few hours, but once you closed the windows it would be back up to 70 in about 10 hours.
Thanks... My house in a High radon emission on the UK map have a constant ventilation on...Building regs as they told me... The floor seem to have a Radon barrier but I thnk I'm going for the test... @@stargazer7644
Radon will not be a severe issue as the diffusion of radon in will be far outstripped by the passive ventilation air exchange. Buy yourself a cheap Geiger counter online and you can get a baseline figure for outdoors and then monitor in the bunker. No self respecting bunker owner should be without a Geiger counter. 😂

Cuttler, a radiation expert and advisor to the American Council on Science and Health, has co-authored a paper entitled "Threshold for Radon-Induced Lung Cancer From Inhaled Plutonium Data," along with Charles L.

I’m genuinely invested in seeing if the bunker has radon.
Detectors are due out very soon so won’t be long until we receive the results!
not only you. i bet on: just shy of "over the limit".

Radon, baby. What a gas!
Interesting to see the full discussion with Colin!
Very good information too know!! Thankyou! Can this happen anywhere?
Every building everywhere has radon. Usually it’s safe, background radiation, but you can find elevated levels anywhere. Know your risk and do a test!
The house I live in New York has a radon system. It was put in before we moved in when I was young. Weird weird how the whole area is high radon. But only two houses have a system to deal with it.
Me in Ontario Canada: "I think I'll check... OMG"
My wife: "Isn't there a Uranium mine up north?"
Did the same thing here in Australia, but it turns out our radon levels are surprisingly low, despite our uranium mines. Didn't expect that! At least there's one thing here that isn't trying to kill us
Southern Ontario is all glacial till. No radon emissions there.
And your basement isn't a sealed space.
It can migrate through the steel - this is the issue with hydrogen by the way.

Limestone doesn't produce radon.

A 'normal' gas will also penetrate concrete. Radon's ability to do this is not unique, nor is it specific to radiation.

pretty sure i've seen this before, did you guys reupload the same video?
Read the description 🙂
Dose the test plastic soke up the raydon or degrad because of the presence of it? Is there a visual way of seeing radon in a lab or on site?
Alpha particles strike the CR39 plastic and damage it, causing minute “tracks”. They look like tiny bullet holes under a microscope.
@@acmhfmggru Personal Radiation Detector, not Geiger counter. PRDs are much broader spectrum and much more sensitive on average.
