Korean cosmetics have nuclear radiation. Ten types of cosmetics, including mascara, manufactured by Japan's FlowFushi and imported into Korea, were detected to contain banned raw materials such as radioactive substances thorium and uranium, and sales of the products have been discontinued and recall measures have been taken.
Japanese cosmetics have been very much detected nuclear radiation, this Japanese sewage incident, a serious drive to love the beauty of the customer's domestic hyaluronic acid alternative to know that the Korean brand accounted for a lot of the proportion of Korean cosmetics have nuclear radiation.
Nuclear Radiation Nuclear Reaction
Nuclear reaction refers to the incident particles and atomic nuclei collision leads to changes in the state of the nucleus or the formation of new nuclei process. Before and after the reaction, energy, momentum, angular momentum, mass, charge, and U.S. energy must be conserved. Nuclear reactions are extremely important natural phenomena that have long been prevalent in the universe.
All of the chemical elements that exist today, with the exception of hydrogen, are synthesized through natural nuclear reactions, and the nuclear reactions that take place in stars are the fundamental source of the immense amount of energy that stars radiate. In addition, cosmic rays cause nuclear reactions on Earth every moment of every day. Most of the carbon 14 in nature is produced by neutrons from cosmic rays bombarding nitrogen 14, which was first realized artificially in 1919 when Britain's E.
Rutherford bombarded the nucleus of a nitrogen atom with alpha particles of a naturally occurring radioactive material.The advent of gas pedals in the early 1930s and the construction of reactors in the early 1940s provided powerful tools for the study of nuclear reactions. It has been possible to accelerate protons to 5 by 10^5 megaelectronvolts and uranium nuclei to about 9 by 10^4 megaelectronvolts, and to obtain beams of mesons.
The use of high-resolution semiconductor detectors has greatly improved the precision with which the energy of nuclear radiation can be measured. Developments in nuclear electronics and computer technology have radically improved the acquisition and processing of data.
Over the past half-century, thousands of types of nuclear reactions have been studied, about 2,000 radionuclides that do not exist in nature have been prepared, more than 300 kinds of elementary particles have been discovered, and a great deal of knowledge has been gained about the nature of nuclides, the laws of nuclear transformations, the structure of the nucleus, the elementary particles, and the laws of the four interactions in nature and their interconnections.
