Radium is very radioactive and toxic; the most simple effects are dermatological but an acute irradiation (or intoxication) can lead to death.
Radon gas is a naturally occurring radioactive element which can be produced by the decay of radium (which in turn is part of the decay chain of uranium) present in granitic rocks and shales and also soils derived from these two rock types.
Methane gas is produced by the decay of vegetation in the absence of oxygen. This process occurs in environments like wetlands or landfills where organic matter decomposes anaerobically. Methane is a potent greenhouse gas with more than 20 times the warming potential of carbon dioxide over a 100-year period.
Argon is a noble gas, and thus it is not present in minerals. It is found in Earth's atmosphere in trace amounts and is also produced through the decay of radioactive materials.
The radioactive decay of uranium and thorium minerals in igneous rocks such as granite can cause the release of the gas Radon which is dangerous to humans. The breakdown (anaerobic decay) of biological materials in soils and rocks at shallow depths can also produce methane gas which can be explosive or potentially cause asphyxia by displacement of oxygen at high concentrations.
Carbon monoxide is produced when burning fuels without sufficient air supply. Carbon monoxide is toxic and can be dangerous if inhaled in high concentrations.
This gas is radon.

Radon
Radon is a radioactive gas that can cause cancer.
Methane (the principal component of "natural gas"), produced by the decay of organic waste.
The extremely dangerous Radon (my favorite element).
Methane gas is produced by the decay of vegetation in the absence of oxygen. This process occurs in environments like wetlands or landfills where organic matter decomposes anaerobically. Methane is a potent greenhouse gas with more than 20 times the warming potential of carbon dioxide over a 100-year period.
That'd be radon
Radon can cause cancer.
