Radon is a radioactive noble gas whose repetitive inhalation is a leading cause of lung cancer, contributing to an estimated 16% of all lung cancer cases diagnosed globally. As radon progresses along its radioactive decay series, it emits alpha particles , a type of high linear energy transfer...
Radon (Rn) is a chemically inert gas with atomic number 86 in the periodic table. The most stable isotope is radon-222 from the decay series of uranium-238. The half-life of radon-222 is 3.8 days. The short-lived daughter products of the noble gas radon are itself radioactive isotopes ...
all of them radioactive. Each is produced by decay of a radium isotope parent within one of the238U,235U, and232Th decay series. Rn is colorless, odorless, and generally unreactive in the natural environment. The longest-lived isotope,222Rn, is the most abundant, although220...
222Rn and its Decay Products 222Rn is preceded in the 238U decay series by radium (226Ra), which has a half-life of 1600 years. 226Ra decays to stable lead (206Pb), producing a chain of radioactive isotopes of solid elements. The decay chain of 238U is shown in Figure 1. Sign in...
Provides comprehensive data for each element of the periodic table of elements including up to 40 properties, names in 10 languages and common chemical compounds. Information also provided for 3,600 nuclides and 4,400 nuclide decay modes.
Isotopes of radon There are thirty four known isotopes of Radon (Rn). The most stable isotope is 222Rn, which is a decay product (daughter product) of 226Ra,
1Introduction In the atmosphere, gaseous radon-222 (t1/2=3.8 d) produces a series of decay products,lead-210(t1/2=22.3 a), bismuth-210 (t1/2=5.01 d), andpo... W Yang,M Chen,Y Huang,... - 《Acta Oceanologica Sinica》 被引量: 23发表: 2006年 Radiological Health Implications of...

It is produced during the radioactive decay of radium-226, itself a decay product of uranium-238 found in many types of crustal materials, that is, rocks and soils. Rn-222 has a short half-life (3.8 days) and decays into a series of solid particulate products, known as radon progeny ...
