(1) This helium produced by radioactive decay, called radiogenic helium, consists of pure 4He.

(2) Radiogenic studies indicate that there have been metasomatic enrichment events of comparable antiquity in the mantle.

(3) If a planet remains very cold, the radiogenic argon remains trapped inside the potassium-bearing minerals in which it is formed.

(4) "Radiogenic decay is at a constant rate over the aeons, which can be measured by physically counting particles, " explained Bouvier.

(5) Reliable information of the radiogenic heat production for the use in thermal modelling now can be derived quickly using only standard GR (API) readings.

(6) The radiogenic heat production rate in the upper crust decreased with the increasing depth. However, they were distributed uniformly within the depth scale of sedimentary basin.

(7) For radiogenic injury, CSF has both protective and therapeutic effects.

(8) Cancers induced by ionizing radiation are called radiogenic cancers or radiogenic neoplasms.

(9) After modification of sample tube, the content of radiogenic Ar increases and reproducibility and accuracy of standards is better.

(10) The Yamansu Formation has more radiogenic lead than the Qi'eshan Group and also shows the weak enrichment character.

(11) Calculations of radiogenic cancer risk are based on the risk projection models for specific cancer sites.

(12) These coefficients have been applied to calculate the radiogenic cancer risks for specific organs and radionuclides under different exposure scenarios.

(13) Radiogenic heat, even from a fairly deep - seated uranium orebody, could be measured.

(14) The portable type of isotopic radiogenic X-ray fluorescence analysis is a kind of method of instrumental analysis without the destructive effect on the samples.

(15) The radiogenic lead of coal fly ash is obviously higher than that of gasoline and diesel oil(Sentencedict.com), which can serve as the discrimination criterion to distinguish the aerosol lead sources.

(16) Using data gathered from other sources on potassium—the other major element—they were able to estimate that radiogenic heat accounts for half of the heat produced by the Earth.

(17) So, there was no evidence of incidence increment of radiogenic cancer in workers exposed to low-level ionizing radiation.

(18) The lead isotope study shows that ores of the Mujiazhuang copper deposit and the host rocks contain very high radiogenic lead.

(19) Estimates have been made based on the expected chemical composition of the interior, but we've never actually measured the radiogenic contribution.

(20) Until now. A paper published last week in Nature Geoscience reports the results of recent work using neutrino detectors to quantify the radiogenic production of heat.

(21) Despite the disturbing number of abnormal births and other radiogenic illnesses affecting the human population, life below the surface of Rongelap seemed to be quite healthy in 1996.

(22) In addition, reference is made to the novel techniques of measuring radiogenic heat.

(23) So, using the least optimistic number, we might expect about ten radiogenic cancer deaths in this population.

(24) This study provided scientific basis of using Siwu decoction for the treatment of radiogenic immunodeficiency.
