Is radon safe when breathed in?

Under the app's default Cautious lens, radon when breathed in rates Swap: the app would put this near the top of your swap plan. 1 sourced concern counts (suspected carcinogen, consensus tier). This is research with sources, not medical advice.

What do the Clean, Low, Watch and Swap levels mean?

They are cut from a continuous concern level the app computes from the sourced claims that the chosen evidence lens shows: each claim counts its concern class, tier weight, confidence and dose relevance, combined worst-first with a decay so one serious finding outweighs many small ones, then scaled by how much of the substance reaches you in this use. Clean is below 0.35, Low below 1.1, Watch below 2.0 and Swap above that, on a 0 to 3 scale.

Where it turns up: radioactive gas, dissolves from soil. Detox My Life researched radon under 2 different uses, because the same substance means something different in each. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

ConsensusSuspected carcinogenconfidence 100%

Radon in drinking water is classified as a human carcinogen (Group 1 by IARC) and increases the risk of lung cancer primarily due to its release into indoor air during household water use, and to a lesser extent, stomach cancer from direct ingestion.

Why here: When groundwater containing radon is used for activities like showering, washing dishes, or cooking, the radon gas can escape from the water and accumulate in indoor air, leading to inhalation exposure. Some radon also remains in the water and is ingested.
What would have to be true: Exposure occurs through drinking water from underground sources (wells) that contain radon. The EPA estimates that radon in drinking water causes about 168 cancer deaths per year in the U.S., with 89% from lung cancer due to inhalation of radon released from water into indoor air, and 11% from stomach cancer due to ingestion. The EPA has proposed a maximum contaminant level (MCL) of 4,000 pCi/L for community water systems, or 300 pCi/L if states do not have enhanced indoor air programs. The WHO recommends a radon concentration in drinking water not exceeding 100 Bq/L (approximately 2,700 pCi/L).
The other side: The risk of lung cancer from radon released from water into indoor air is generally considered smaller than the risk from radon entering the home from soil gas.

ConsensusSuspected carcinogenconfidence 100%

Inhalation of radon and its radioactive decay products causes lung cancer in humans.

Why here: Radon is a naturally occurring radioactive gas that can seep into and accumulate in indoor environments, such as homes and buildings, leading to chronic inhalation exposure for occupants.
What would have to be true: Chronic inhalation of radon gas and its decay products at concentrations commonly found in residential settings, with the risk increasing proportionally with increasing exposure. The World Health Organization (WHO) recommends a national annual average residential radon concentration reference level of 100 Bq/m³ (2.7 pCi/L), and the US EPA recommends taking action to reduce radon levels at or above 4 pCi/L (150 Bq/m³).
The other side: Not applicable.

Not researched here

The engine has no dossier for radon when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.

This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.

Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
