Results of I-Xe analyses have been obtained from meteorite samples that experienced different extents of thermal processing in the early Solar System in order to help characterise the movements of iodine and xenon in the early Solar System and constrain the timing of these movements using the I-Xe chronometer. The most primitive material analysed give I- Xe ages between - Myr, slightly later than reported Mn-Cr ages. This may support the ideal of radial heterogeneity of 53Mn in the early Solar System. However differences could also be due to variations in the samples analysed. Future analyses of I-Xe and Mn-Cr ages in mineral separates from the same R-chondrite are recommended in order to investigate this hypothesis. This implies either later accumulation of material or slower cooling in a larger body.

The point is that the tiny amounts produced by the decay of Iodine would be harmless. If the amounts of Xenon were large enough to be harmful, a person would already be dead from the radiation. For what it's worth, I found this page home. It claims that the same would be true even in a fantasy universe where Iodine decays to Arsenic.

The periodic table of the elements

These radionuclides—possibly produced by the explosion of a supernova—are extinct today, but their decay products can be detected in very old material, such as that equipment constitutes meteorites. By measuring the decay products of equipment radionuclides with a mass spectrometer and using isochronplots, it is possible to determine relative ages of different events in the early history of the solar system. Dating methods based carbon extinct radionuclides equipment also be calibrated with the U-Pb method to equipment absolute ages.

They found xenon in the residue left over from evaporating components of liquid air. This led him to the invention of the xenon flash lamp in which light is generated by passing brief electric current through a tube filled with xenon gas. In , Edgerton was able to generate flashes as brief as one microsecond with this method. He tested the effects of varying the breathing mixtures on his subjects, and discovered that this caused the divers to perceive a change in depth. From his results, he deduced that xenon gas could serve as an anesthetic.
