The 2024 UNSCEAR report has updated its methodology for evaluating indoor radon concentrations, part of the most comprehensive global assessment to date of public exposure to ionising radiation.
Drawing on extensive literature review (2007-2022), it reconfirms: natural sources, including radon, remain by far the top contributors to public exposure worldwide.
Worth a read. More on page 26: https://buff.ly/612i4NS

Why do indoor radon levels change over time? The 2024 UNSCEAR report has answers.
Studies from 2006-2022 show building changes are key: preventive measures & ventilation push radon down, airtight energy-efficient retrofits can push it up if ventilation isn't addressed.
Today's buildings shape tomorrow's radon exposure.

I was outside for ten minutes hours ago. Seemed smoky but okay. But it just now hit me full on and I'm in bed with an asthma attack. Please take this seriously. Even inside the house is smoky, and we're all the way in Virginia. This is bonkers bad.

Basement is now over 15 ug/m^3 for PM2.5. Maybe I should get my Corsi-Rosenthal box running again.
I do have a commercial air purifier running down there but it doesn’t seem to be effective enough.

I always assumed my shitty summertime sleep was because of the temperature, but I cracked a window last night and it might actually be the CO2.
The AC generally does not run after I go to bed, unlike the furnace. CO2 levels were way lower and peaked much later. 1300 PPM at 6 am vs 1800 ppm at 4 am. With the windows closed I hit 1300 ppm 2 hours after getting in bed.
I sleep with the door closed because it’s weird to have it open.

Morning run done — 8.5 km — and straight into ERA Workshop recap mode 🏃🎙️
Yesterday in Bergamo: four talks on radon in water, RadonNet instruments, gamma spectrometry + indoor air risk assessment, and soil gas by Matej Neznal. Roundtable with ~40–45 on site and ~20 online. ERA AGM, Executive Committee meeting, rooftop dinner. ☀️ 25 degrees in Bergamo.
Science doesn't stop. Neither does the training.

Heat Recovery Ventilator (HRV) — Operating Principle
A recuperator (heat recovery unit) transfers heat from exhaust air to incoming fresh air without mixing the two streams.
---
How It Works
Two airflows:
Exhaust air (warm, from indoors)
Supply air (cold, from outside)
They pass through a heat exchanger:
separated by plates or channels
no direct mixing
heat transfers through the material (conduction)
Result: → supply air is preheated
→ exhaust air is cooled
→ overall heat loss is reduced---
Types of Recuperators
1. Plate Heat Exchanger
aluminum or plastic plates
efficiency: ~60–90%
no moving parts
2. Rotary (Wheel) Heat Exchanger
rotating drum
transfers heat and some moisture
efficiency: up to ~85–90%
3. Counterflow Heat Exchanger
air streams move in opposite directions
highest efficiency: up to ~95%
---
What Is Transferred
heat (primary)
sometimes moisture (in enthalpy units)
---
Efficiency Example
outside: 0°C
indoor: +22°C
after recovery: ~16–20°C
---
Advantages
reduced heating energy demand
continuous ventilation without major heat loss
improved indoor air quality
---
Limitations
frost formation in winter (needs bypass or preheater)
filter maintenance required
upfront cost
---
Core Idea
A recuperator doesn’t generate heat — it recovers and reuses it.
