Radium is very radioactive and toxic; the most simple effects are dermatological but an acute irradiation (or intoxication) can lead to death.

Radon Gas
222Rn
Radon is a dangerous gas released by rock and soil. It is colorless, odorless, and tasteless, making it difficult to detect without specialized equipment. Prolonged exposure to high levels of radon gas can increase the risk of developing lung cancer.
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.
The presence of hydrogen sulfide gas in the cave can cause it to smell like rotten eggs. This gas is produced by the decay of organic matter in the absence of oxygen. It can be toxic in high concentrations.
At the positive electrode, oxygen gas was produced.
When aluminum reacts with sodium hydroxide, hydrogen gas is produced along with sodium aluminate as a byproduct.
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.
This gas is radon.

Yes, radon is a decay product in the uranium, thorium and actinium decay series.
Isotopes of radon (Rn)
Radon
Radon is a natural chemical element; it can be found inthe radioactive decay series of uranium, thorium.
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).
