Nuclear fission

The meaning of irradiation is the process of exposure to radiation, such as using gamma rays for sterilization. There have been many controversies about food irradiation. Some people say that using nuclear technology on food can cause harm to the body. But I believe that using nuclear technology is the best way to remove any diseases on food to cause less harm to the human body. Irradiation can also be used to preserve nutrients in food and kill microbes that destroy them. Using preservation procedures

Silicon Come one! Come all! Today I would like to talk to you about our new product, Silicon! Silicon has a symbol which is Si. What's the relationship between Silicon and its symbol you ask?The relation between Silicon and its symbol is the first two letters of the beginning of the word Silicon. Silicon was discovered in 1824 by Jöns Jacob Berzelius in Stockman, Sweden. Silicon is the 14th number in the periodic table. It has 14 protons ,electrons and 12 neutrons. It is in period 3 and also

Have you ever wondered what happens to all the atoms in our bodies when we grow, or even how we grow? Have you ever wondered why we grow? I have always wondered about those things. Without atoms we would not exist neither would the world. Atoms make up everything. Isn't it crazy that these tiny particles make up everything around you! Atoms are really important because of that. We know that atoms make up everything around us. So we need to know what is in an atom. First there is the nucleus the

Bone Scan A bone scan is an imaging study of your bones. It is used to identify and diagnose bone problems. You may have this test to check for: • Cancer in your bones. • A broken or cracked bone. • Bone infection. • A cause of bone pain. • Certain other bone diseases. For this procedure, a small amount of a radioactive substance (radiotracer) is injected into your blood. Your bones will absorb the radiotracer for a short time. The radiotracer gives off radioactive energy. This energy

different properties from the original or parent substance. In addition to this formation, alpha and beta particles are emitted from the nucleus of the parental compound. Respectively, Rutherford and Soddy each received a Noble prize in the field of nuclear chemistry due to their outstanding scientific findings. In 1908, Rutherford was awarded the Noble prize for his investigations concerning the decay of elements and the chemistry of radioactive compounds. Following this, Fredrick Soddy then received

conducts in the Heaven laboratory involves finding safe methods of disposing nuclear waste, through studying the properties of actinides. Actinides are f block elements, that have high oxidation states and experience no shielding in their 5f orbitals. Also, heavier actinides have electronic properties similar to Lanthanides, where the atom gets closer towards reaching the speed of light. As a result of the velocity and nuclear charge, a decrease in the Bohr radius expands the actinide orbitals, making

MRI can have an impact on the human body as the tissues in the body contain a large amount of hydrogen and the nucleus of the hydrogen has a positively charged proton which can behave like a magnet. MRI scan is used to produce a detailed image of the inside of the body. This is done using strong magnetic fields and radio waves. It is a heavy equipment which uses advanced technology and many computer systems. The nuclei is polarised using the magnetic fields provided by the electromagnets and a huge

Introduction The A simple definition of the word radioactiveis to have or develope a strong and dangerous form of energy. This could also be named radiation. A radioactive substance incvolves a very harmful form of energy that is developed betwen nuclear reactions. In the book "The Radioactive Boyscout" by ken Silversteint, there are several examples of radioactive substances being produced. The main character in the book is very as the title says "radioactive" Key Idea 1 David Han who lives in

Atoms in Electrons “Energy levels in Atoms exist all over the world. Some atoms consist of protons and neutrons making up a nucleus; they are surrounded by electrons. Rutherford made designs and conclusions to develop his nuclear atomic model. Although Rutherford’s model couldn’t explain other properties of elements, such as why metals or compounds of metals give off colors when the flame is heated” (Wilbraham et al 136). John Dalton. (Early nineteenth century) He combined an idea of elements with

Atoms are made up of electrons, protons and neutrons. Protons have positive charge; electrons have negative charge and neutrons are neutral. The magnitude of charges of protons and neutrons is the same. Protons and neutrons are found in the nucleus, while the electrons moves around it. Mass number is addition of the protons and neutrons. Atomic number is the number of protons. [1] The mass of an atom is less than the number we obtain by adding up the masses of all the protons and neutrons. This is
