RADIATION DETECTION IN VEGETABLE LEAVES: A COMPARATIVE CASE STUDY IN COASTAL AND HINTERLAND REGIONS OF AKWA IBOM STATE BY Godfrey T. Akpabio‚ Ime E. Essien And Bassey E. Bassey. Department of Physics‚ University of Uyo‚ Uyo. ABSTRACT Radioactive radiation level was detected for five samples of vegetable leaves namely: Water leaf‚ Fluted Pumpkin‚ Editan Lasientera africana and Afang Gnetum africanum. These vegetable leaves were collected from Uyo (interland region) and Ibeno

My major academic and career goal is to attend college‚ and become a Radiation Therapist. My grandfather was diagnosed with stage four colon cancer when I was nine years old‚ and was put through various stages of radiation therapy. This sparked my interest in the medical field. Ultimately due to my enjoyment of working with people facing difficult circumstances and helping them through the rough times I came back to Radiation Therapy. While my grandfather was administered the therapy‚ he met truly

Some of the greatest medical advancements in the modern age involve the use of many different types of radiation. Radiation therapy is used in treating multiple different types of cancer‚ and radiation from certain elements are put in X-ray tubes to save countless lives and prevent permanent injury wherever possible. Many organisations also use it for security‚ as well as the general use in the everyday home. These advancements and many more were based on the work of Marie Curie‚ renowned female

overwhelming obstacles for a greater cause is a hero. While numerous people can be considered a hero‚ it primarily takes perseverance‚ determination‚ courage and motivation. This is illustrated by the revolutionary acts of Mahatma Gandhi and Stephen Hawking‚ as well as the life-changing deeds of everyday heroes like Lisa Chesser. Mahatma Gandhi was a leader of India’s independence movements; he persevered to advocate for Indians rights at home

Radioactive emissions are electromagnetic radiations which occur due to the spontaneous disintegration of unstable nuclei. Natural elements with atomic number greater than 83 and isotopes of some lighter elements are found to be radioactive. They are categorized as alpha‚ beta and gamma radiations. Alpha particles are positively charged helium-4 nuclei ‚ beta particles are high energy-high speed electrons while gamma rays unlike alpha and beta radiation have no mass and charge and are short electromagnetic

Radioisotopes: When radiation collides with molecules in living cells it can damage them. If the DNA in the nucleus of a cell is damaged‚ the cell may become cancerous. The cell then goes out of control‚ divides rapidly and causes serious health problems. Radiation warning symbol The greater the dose of radiation a cell gets‚ the greater the chance that the cell will become cancerous. However‚ very high doses of radiation can kill the cell completely. We use this property of radiation to kill cancer

in the discharge tube. A fluorescent glow appeared on the glass opposite to cathode. The colour of glow of the glass depended on the type of glass‚ it being yellowish-green for soda glass. The cause of this fluorescence was attributed to the radiation which appeared to be coming from the cathode. These cathode rays were discovered‚ in 1870‚ by William Crookes who later‚ in 1879‚ suggested that these rays consisted of streams of fast moving negatively charged particles. The British physicist

Stephen Hawking wrote a lot of papers‚ though. Most dealt with the same sort of heady concepts as his last‚ and few received such an inordinate amount of attention. Claims that the paper make predictions for the end of universe‚ or could prove the multiverse exists abound. But it’s worth remembering that the things Hawking thought and wrote about are abstract‚ they exist largely in the realm of theory. Even more well-known concepts like Hawking radiation have continued to elude scientists‚ so drawing

The Big Bang Theory What is the Big Bang Theory? The Big Bang is the dominant (and highly supported) theory of the origin of the universe. In essence‚ this theory states that the universe began from an initial point or singularity which has expanded over billions of years to form the universe as we now know it. In 1959 a survey was conducted of scientists across America concerning their understanding of the physical sciences. One particular question asked “What is your concept of the age of
