Isotope

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…

There is a steadily growing consensus that recent human activity has had such an impact that it has shifted the Earth into a new geologic epoch of our own making. The advent of this epoch, known as the Anthropocene, has generated much discussion and tension between the various science disciplines. The major issue being discussed is whether there is a need for a new era covering the last three centuries of human impact on the planet. Defining this epoch, in terms of both time and space, has also…

People are awake the majority of the day, but a large portion of the day is consumed by sleeping. A good night’s rest is essential because without an appropriate amount of sleep, the hours spent awake can become impacted. Unfortunately, sleep disorders can affect a person’s sleeping abilities. Narcolepsy is one example of a sleep disorder that will affect someone at night and through the day. Narcolepsy can be defined as a neurological disorder where the person experiences daytime sleepiness…

Prize twice in chemistry and in physics. Having one of the world’s most brilliant minds, Marie Curie discovered the field of atomic physics, polonium, leading to the development of the atom bomb, and radium, which paved the way for use of radioactive isotopes in the medical field. Moving from Poland to Paris in 1893, Curie finalized a masters degree in physics and math. Shortly after, the Society for the Encouragement of National Industry paid her to study the magnetic properties of steel,…

The CSI (Miami) team responded to a report of a body found lying near a syringe. Further investigation by the CSI team revealed the man was lying on a wad of money and near a backpack. The team decided robbery did not appear to be the motive in the victim’s death. Identification found in the dead man’s wallet said he was Carl Aspen/Victim #1, a junkie and a minor thief. The team’s perception of how Victim #1 died concluded with robbery not being a motive, therefore, they awaited the medical…

North Korea is no stranger when it comes to nuclear suspicion. This is evident in their history of behavior and lack of disclosure in regards to their use of nuclear activity. On December 31st 1992 both North Korea and South Korea merged to create an agreement banning nuclear weapons. According to the text, both parties were allowed permission to inspect “objects on the other’s territory”. However, the conflict with the agreement was there was not a set procedure explaining how these…

What are the benefits, issues, and differences between CAT scans, X-rays, and MRIs? The discovery and research of radioactive isotopes and radiation had a major impact on the creation of more elements and the grand advances in the science and medical fields. Of these advancements some of the most prominent uses of these technological advancements is the use of CAT scans, X-rays and MRI. Which are all used to get a better look at the insides of the human body, and to further diagnose serious…

Cognitive psychology is the study of human mental processes that occur within the mind. It looks at such internal processes such as, memory, perception and attention. It came about in the 1950’s as a result of the behaviourist approach being flawed; internal mental processes cannot be observed. Therefore, from this an alternative method of looking at the physiological side of the brain had to emerge. Cognitive neuroscience was then born to identify the neural mechanisms, which are responsible…

analysis can even show males consuming more protein than females. The scientific analysis alone is not enough to satisfy the question. In order to fully understand the scientific results, the data must be contextualized and answer why protein and isotopes show up more prominently in one group over another. The data portrayed status and gender as important social components that are rewarded with access to important foods. A possible explanation for males consuming more protein than females could…

History and Controversy of Nuclear Power The creation of nuclear energy has changed the world but, it has affected someone people a little bit closer. Lindsey Schiller, a registered nurse, and her husband and two children have been living next to a nuclear power plant almost a decade now. Currently neighboring the Limerick Generating Station nuclear energy facility in Pottstown, Schiller jokingly states “We kid around when we get really big flowers ... we 're under the power plant, and I kid…
