Over the years, technology has been greatly improved affecting the lives of all people. Technology has changed the way people socialize and perform their daily activities. Technology is one of the main driving forces of the future. Technology has enhanced the quality of life for humans. There are many different views of technology.…...
Fission and Fusion
Words • 655
Pages • 3
In natural radioactive decay, an unstable isotope of an element decays into a different atom and an emission (alpha/beta particle, or energy in the case of gamma/ radiation). This is a spontaneous natural process with a random rate. Nuclear fission is also the splitting of a nucleus into two smaller parts, but each of these is an element in itself. Fission does not happen spontaneously; it requires a trigger. An unstable nucleus bombarded with a neutron will "elongate and divide…...

A new atomic theory, in which all atoms of the same element are identical to one another and equal in mass, was proposed by the scientist Dalton. Although the theory had its flaws and was simple, it was revolutionary. Scientists became able to study the actual structure and mass of atoms after the discovery of radioactivity. Soon, isotopes were discovered, as atoms of the same element which have been built up to have different masses. Purpose The purpose of this…...

Carbon 14 Dating
Words • 3710
Pages • 15
Archaeologists utilize a number of methods to examine data from the past. One clinical tool assists to analyze the radioactive decay of chemical aspects discovered in plant and animal stays, pottery, and even rocks. Radiocarbon dating, also referred to as carbon-14 dating, has become among the most essential radioisotope dating approaches archaeologists employ. This scientific tool, very first established by Willard F. Libby in the late 1940s, started with the discovery of the isotopic carbon-14 atom. Following this discovery, researchers…...

Harmful Effects of Television
Words • 434
Pages • 2
Television is a medium of communication, information, and entertainment. It is the most popular system for transmitting images and sounds to people. In fact, television can have negative effects due to radioactivity, falsehood and obsession. First of all, television releases radiation. A lot of people believe that television is harmless. However, scientific studies prove that unlike any other household equipment television sends out a lot of radioactive rays. Indeed, radiation deteriorates vision. As well, it can damage it. For example,…...

Pages • 5
Francium (pronounced FRAN-see-em;formerly known as eka- caesium and actinitium K) is a chemical element that has the symbol Fr and atomic number 87. It is the second rarest naturally occurring elements after astatine. Francium is a highly radioactive metal that decays into astatine, radium and radon. As an alkali metal, it has one valence electron. Francium was discovered by Marguerite Perey in France (from which the element takes its name) in 1939. It was the last element discovered in nature,…...

Introduction Industrial accidents can occur at anytime, anywhere in the world which may result in loss of lives or injuries to workers and can cause significant damage to the surroundings. Thousands of employees lose their limbs, vision and their lives each day due to the accidents that happen in industries. (Aswathappa, 2005) Industrial accidents cannot be predicted. Most of these happen as a result of human negligence. Accidents occur if the workers are not properly trained to use the industrial…...
