Urban decay

Over the last few decades technology has made great progress in the medical field, helping to discover new treatments and cures for problems affecting the human body. Anti-biotics are being used to fight off infection, multiple radiation beams are being used instead of just one for tumor treatment to help patients avoid harmful radiation, and many more that were thought impossible just a short while ago. But even in cases where there is still no definitive cure, technology has advanced so much…

Scientists use radiation in more forms than the average person realizes. With new technology these developments form new ways of living. Agriculture is not recognized as a big part in nuclear science. George de Hevesy was the first to practically use an isotope in 1911. We can thank him for the new advancements in fields of nuclear technology. The food you eat probably was altered using a form of neutron or gamma irradiation. Radioisotopes have changed the way we live, through all fertilizers,…

These radioactive elements decay spontaneously into different elements while also releasing ionizing radiation from the nuclei. The radiation most commonly emitted from these radioactive elements are alpha (α) particles, beta (β) particles, and gamma rays (γ). An alpha particle consist…

Radioiodine production Radioiodine is defined as a radioactive isotope of the chemical element Iodine. Although there are at least 37 different Iodine radioisotopes, only four of them are used as tracers or therapeutic agents in medicine; these are 123-I, 124-I, 125-I, and 131-I, with the latter being the most common in clinical practice. Essentially all industrial production of radioiodine isotopes involves four aforementioned radionuclides. History of radioiodine production and usage The…

PET is a nuclear medicine, working imaging ability that creates a three-dimensional image of functional processes within the human body. [1] First, chemicals which emits gamma radiation are injected into the human body, then; the system detects pairs of gamma rays emitted indirectly by a tracer to show images of bones and organs. These substances are injected into the body, and are usually tagged with a radioactive atom.[1] Doctors use this device to create images of bones and organs of the…

technetium-99m is an isotope of the artificially and it has many characteristics for nuclear medicine scan the first one it has a half-life of six hours and it decay by process called “ isomeric ” and emit low energy of gamma rays and this helps to easily exit the body and can be detected accurately also emit beta rays but without high energy radiation dose to the patient is low . It has different number of…

Radio isotopes: The help and the hurt Radio isotopes are used constantly in the medical and industrial world. They can be useful when diagnosing human and other animals with diseases, and in treating them for many diseases. However, the use of radioisotopes can increase the demand for nuclear power, and have many negative side effects on humans and other organisms. Many radio isotopes are relatively harmless in the body. They can be used to view the inside of your body, allowing doctors to…

Urbanization is a complex spatial process that converts rural land uses to urban uses, and causes various impacts on ecosystem structures, function, dynamics, and the livelihoods of human beings. It is expected that by 2030, there will be 2 billion new urban residents. The study also suggests that 90 percent of urban growth is taking place in developing world. A largely rural country, with only 17 percent of the population living in urban areas (Nepal census, 2011), Nepal is urbanizing rapidly.…

We know that radiation is harmful to us, even the sun’s UV waves are know to cause skin cancer. Than why, you may ask, do you think radiation is so good for us when it is so bad for our health? Well, for starters the two biggest types of power right now are Nuclear and Coal. If you have been keeping up with the environmental status coal is not helping the climate. People want to enjoy technology, but that costs power, which comes from coal. How do we balance these two, protecting the…

so having too few means that the link may be too weak to hold it together then having too many means there pushing others off the particles as there are too many attached to the main atom for them to share.Beta particles are formed when the neutron decays and forms an antineutrino particle which contains neutron and a few protons this then leaves a negatively charged beta particle due to the lack of neutrons to hold the particles together which will, in turn, throw the balance of the particles…
