C++ Wage Slave<p>Where in the UK can I buy a domestic <a href="https://infosec.space/tags/RadonMonitor" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RadonMonitor</span></a> that actually works? I don't want to spend a fortune, but I want a device that's reasonably accurate. Have you bought one of these devices and, if so, where did you get it?</p><p>(I've been burnt by <a href="https://infosec.space/tags/Amazon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Amazon</span></a>, which, last year, charged me £75 for a device that's so useless that it's now been recalled. The reviews, obviously, were fine.)</p><p>Edit: people here like <a href="https://infosec.space/tags/Airthings" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Airthings</span></a> and online reviews seem good, so I've ordered an Airthings Corentium. I'll know in a couple of months whether I have a problem and what to do about it.</p><p><a href="https://infosec.space/tags/RadonSensor" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RadonSensor</span></a> <a href="https://infosec.space/tags/radon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>radon</span></a> <a href="https://infosec.space/tags/AskFedi" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AskFedi</span></a></p>
