How long before only 1/16 of the original sample remains? Solution: recognize 1/16 as a fraction associated with 4 half-lives (from 1/2 4 = 1/16) 3.82 days x … Chapter 8, Section 8.2, Question 031 X Incorrect Radon-222 is a radioactive gas with a half-life of 3.83 days. This gas is a health hazard because it tends to get trapped in the basements of houses, and many health officials suggest that homeowners seal their basements to prevent entry of the gas. Radon's most stable isotope, radon-222, has a half-life of about 3.8 days. This seems to be a relatively short half life. So why is there so much concern about radon in homes? To understand completely we should consider the types of radioactive decay.

Radon-222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon.
In radon. Dorn, radon-222 (3.823-day half-life), the longest-lived isotope, arises in the uranium series. The name radon is sometimes reserved for this isotope to distinguish it from the other two natural isotopes, called thoron and actinon, because they originate in the thorium and the actinium series, respectively.

The radioactivity of these radon daughters is measured by detecting the outcoming alpha particles. The most abundant radon isotope is 222 Rn, which itself is a member of the decay chain of 238 U. The decay chain of 222 Rn is shown is figure 2.1. The half-life for each radioactive member of the chain is indicated, as is the alpha-particle energy
Radon is sparingly soluble in water, but more soluble than lighter noble gases. Radon is appreciably more soluble in organic liquids than in water. Chemical properties. Being a noble gas, radon is chemically not very reactive. However, the 3.8-day half-life of radon-222 makes it useful in physical sciences as a natural tracer.

Radon-222 (222 Rn, Rn-222, historically radium emanation or radon) is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial uranium-238 and is the immediate decay product of radium-226.Radon-222 was first observed in 1899, and was identified as an isotope of a new element several years later.
