Ionizing radiation

The satellite measures a type of radiation which is called the cosmic microwave background. It permeates the universe searching for evidence of the events that took place during and after the explosion known as The Big Bang. Very similar to the Cosmic Background Explorer, it spent four years orbiting Earth to detect the oldest light in space, the cosmic microwave background radiation. The four year mission of collecting data was successful and resulted in the…

Does the Steady State Theory or the Big Bang explain the origin of the universe? There are many theories that contribute to the opinions and ideas of how the universe came about approximately 13.7 billion years ago. Two highly debated theories of evolution include the ‘Big Bang Theory’ and the ‘Steady State Theory’, two of which have very different points of view about how the universe came to how it is today. The ‘Big Bang Theory’ discusses how the universe began as a very small, hot and dense…

Foods are exposed to a specific dose of radiation which does not make the foods radioactive. There have been no sign of toxicology or safety issues by irradiating food products. Currently the Food and Drug Administration regulates food irradiation. Types of radiation, duration of exposure and dosage are highly regulated. Any foods that have been irradiated must contain the irradiation symbol on the package. When molecules absorb ionizing energy, they become reactive and form ions or free…

This paper uses the information obtained from four peer reviewed articles about the importins of an abdominal CT scan for the diagnoses of diverticulitis. The paper goes into detail about the features of CT and its ability to accurately demonstrate the bowel wall as well as the surrounding soft tissues structures. It goes in to further detail in explaining the cause, symptoms, and preventative measure for diverticulitis. This paper also focuses on the possibility of other imaging modalities like…

biggest wavelength in the spectrum. This type of electromagnetic radiation is less dangerous than higher frequency electromagnetic radiation at immediate contact as it is non-ionizing however there has been debate over the long term effects of radio-frequency waves on the human body, particularly those which are found in cell phones which are devices that are constantly in contact or very close proximity with the human…

(environmental factors). Endogenous sources of DNA damage include hydrolysis, oxidation, alkylation, and mismatch of DNA bases; sources for exogenous DNA damage include ionizing radiation (IR), ultraviolet (UV) radiation, and various chemicals agents. DNA damage types used for this work are produced by ionizing radiation (IR) and ultraviolet radiation (UV). Ultraviolet (UV) light from sunlight, can make up to 105 DNA lesions (pyrimidine dimers) in cell per day. Pyrimidine…

These threats all effect the development of a baby’s immune system during both the prenatal and neonatal stages of development (Wigle, 2003). Ultraviolet light and ionizing radiation are both types of radiation (EPA, n.d.). Exposure mainly comes from black lights, tanning beds and x-rays. (EPA, n.d.). TCDD is a by-product of the incomplete combustion of fossil fuels, wood and chlorinates organic chemicals. Exposure mainly comes from meat…

Elias Abejo Acute Myelogenous Leukemia Symptoms: Acute lymphoblastic leukemia is a fast-growing type of leukemia that rapidly creates not fully developed immature blood cells. There are three symptoms of acute myelogenous leukemia that require a medical diagnosis or determines that you have acute myelogenous leukemia. The first symptom that will occur in leukemia is fatigue, or extreme tiredness and lack of energy you will feel all the time. You will also have infections that will occur more…

of chemistry so nuclear changes would be included, after he discovered that uranium could disembogue radiation. Not very long after his discovery, Marie Curie began studying in the field of radiation, and completed most of the pioneering work on nuclear changes. Marie Curie discovered that radiation was related to the amount of radioactive element that is present, she also discovered that radiation was a property of atoms. Curie was the first woman to win a Nobel Prize and the first person to…

performed to determine whether processed foods can be sanitized by using great amounts of gamma radiation. A can of various meats was revealed to a radiation amount which was believed to destroy all known types of lifestyle, but the various meats subsequently damaged and D. radiodurans was separated. Since then, this variety has been intensively analyzed for its radiation-resistant qualities. It is known that radiation stages enduring of up to 1,000 times, which would destroy a normal person, D.…
