The Problem of Natural Radioactive Elements

The article presents two opposing views on the origin of natural radioactive elements. According to a view based on the Big Bang Theory, the elements found on Earth were formed by the process of primary nucleosyntase 13.8 billion years ago, with the exception of uranium and other heavy elements that were formed billions of years later under stellar conditions. It follows from this view that throughout the existence of the earth, the global amount of uranium and other primary radionuclides is reduced as a result of natural decay. The reasoning of the proponents of the BB theory is as follows: if the global radioactivity decreases, the problem of the threat decreases and one only needs to get used to the newly discovered natural phenomenon. There are even official regulations that exclude ionizing radiation from radon in the calculation of the limit dose. The Primary Forces of Nature theory presents a completely different view. Considering the analogous influence of gravity on the formation of the globs of the solar system, the logical explanation of the phenomena of geological activity are thermonuclear processes, such as on the sun. Hence the conclusion that the elements chemical are now created in the core of the Earth in the process of thermonuclear synthesis. The problem is serious because there is an accelerated growth of new igneous matter containing the created elements, and the ionizing radiation of natural radionuclides is the main factor responsible for the radioactivity level of the human environment.

Research on the Effects of the Contents of Radioactive Elements on Granularity and Climate Change:An Example of SZK1 and SZK2 Drill Holes Strata in the Fuzhou Basin

Based on the content of radioactive elements (U, Th, K) of strata in two drill holes in the Fuzhou basin, and combined with the result of spore_pollen analysis, the relationship between radioactivity and lithology and deposit environments is discussed and the results show that the content of radioactive substances is related to the granularity and lithology in sediment, and it is higher in argillaceous sediment (e.g. silt and clay), lower in sand sediment and in the middle in gravels between the above two kinds of sediment. The content of radioactive substances is also related to paleoclimate. A warm and humid environment is propitious to the deposition of radioactive substances, while a cool and dry climate is just the reverse.

Interpretation of Water Samples by Correspondence Analysis for Radioactive Elements in the Northern Coast of Oman Sea

Oman Sea is connecting belt between the Indian Ocean and Persian Gulf.Because it strategic and environmental aim,presence of natural radionuclide ^(226)Ra,^(232)Th,^(40)K and ^(137)Cs as man-made element is considered.Water samples were taken from 36 marine spots at the coastal strip from Hormoz canyon to Goatr seaport in the northern coast of Oman Sea.Correspondence analysis is used to identify variation and relationship between samples(Q-mood analysis)and variable(R-mood analysis)based on approximate χ^(2)distances.Radioactive elements(^(226)Ra,^(232)Th and^( 40)K),physical(temperature,pH,turbidity,conductivity,special density)and chemical(salinity,oxygen and chlorophyll)parameters of water for 36 samples handled by correspondence analysis,there are two outstanding result,(1)Radioactive elements show high correlation in factors by greater eigenvalue,and (2)some of the samples such as W13,W24 and rather W02,W05 and W12 show highest activity from Radioactive elements and also temperature and conductivity show nearest relation with them in many factors.

Radiogenic geothermal systems of Bangka Island,Indonesia:Implications of high heat production and tectonic framework

The presence of geothermal manifestation in Bangka Island(Southeast Sumatra,Indonesia)with the absence of Quaternary volcanic activity and also relatively low seismicity events has raised intriguing questions on the control of the geothermal system in this area.As the regional tectonic setting of Indonesia volcanic geothermal systems has been known,that of non-volcanic geothermal systems such as radiogenic system become an issue to be investigated.This study reports the geochemistry and petrography analysis of Triassic granite related to radiogenic production at the vicinity of hot springs in Bangka Island.Surface temperatures of the Bangka hot springs range from 37 to 70.7 and pH values vary between 5.6 and 7.5.These hot springs are discharging either in close to massive granite bodies or occur in between two major NE-SW striking faults zones,i.e.,Pemali fault and Payung fault.Our results indicate the average radiogenic heat production of Late Triassic Klabat granite in the northern area ranges from 28.5 to 38.34μWm^(-3)and the southern area ranges from 28.3 to 49.5μWm^(-3).In comparison to similar granite belt located in Malaysia,heat production of granitoid in Bangka hot springs is four times higher,possibly due to their different granite origins.
