Radon and its decay products compose most of ionizing radiation (Girgzdys, Ulevicius 1985; Gesell 1983).
In the environment, thorium and its compounds do not degrade or mineralize like many organic compounds, but speciate into different chemical compounds and form radioactive decay products. Analytical methods for the quantification of radioactive decay products, such as radium, radon, polonium and lead are available.
Due to a larger water plant surface per weight unit, since vascular plants are also attributed to submerged plants, their exposure to [sup.238]U and its decay products is the largest (Figs 1 and 2).
Thus, the use of [sup.226]Ra alone to predict total radioactivity concentration in liquid drilling wastes can underestimate the increase in levels that will occur over time and neglects the potential for the bioaccumulation of alpha- and beta-emitting decay product radionuclides in bacteria, plants, and higher organisms.
Fisher of PNNL finally constructed a cage for the alpha emitter radium-223, a decay product of actinium-227.
But researchers calibrate PET scanners with a decay product of germanium-68.
One of the isotopes, neodymium-142, represents in part the radioactive decay product of a form of the element sumarium, which was present only during Earth's earliest epochs.
Its draft risk assessment points to radium-226, a decay product of uranium-238, as the principal isotope of concern.
It's indoor radon exposure that poses the greatest risk due to the increased likelihood of inhaling radioactive decay products in a confined space.
Even for people who have never smoked a cigarette, exposure to radon and its decay products can lead to lung cancer.
The radioactive gases, radon (222Rn), as well as its decay products present in the environment are considered to be the main causes of radiation dosage to the community from radioactive materials.
