Radiation is the reactions caused by kinetic energy passing from one place to another. Radiation has been part of the human environment since the existence of Earth. Some sources of radiation are natural. However, others are artificial. Terrestrial sources of radiation are natural and come from the earth. They originate from radioactive materials in the earth's crust. The sun's rays are also a natural form of radiation called cosmic rays. (Statkiewicz-Sherer, 2017). Artificial sources of radiation create Electromagnetic Fields (EMF) that are created by humans. EMF's could be hazardous to people who come in close contact with them. X-rays and gamma rays carry ionizing radiation and have the highest charge. Non-ionizing radiation also referred as mid frequency radiation found in devices people use every day. Low-frequency radiation found in household appliances, Television signals, and local wireless networks is also known as background radiation. (Electro Magnet Fields and Cancer, 2016).
Radios and Televisions Radios and Televisions found in homes around the world use electromagnetic radio waves to receive broadcasting signals. Local broadcasts use Frequency-modulated radio signals and antennas with frequencies that are below EMF regulation limits. These antennas are usually near areas accessible to the general population they do produce hazardous levels of EMF's. Amplitude-Modulated (AM) radio signals are used to broadcast over a long distance and use large
Radiation (also known as nuclear radiation) refers to particles or waves emitted by radioactive substance. Nuclear radiation comes from the waves from a nucleus. Ionising radiation can
Electromagnetic Radiation – A form of energy composed of waves of electric and magnetic changes (from electrically charged particles). It deals with
Radiation was discovered in 1895 by Wilhelm Roentgen during a scientific experiment. Roentgen, classified radioactivity into three concepts: negative, positive, and electrically neutral. Radiation- is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Technology is created with radiation and humans are exposed to the aspect daily with tons or material; especially in the doctor’s office and everywhere else.
The new United States Coast Guard Radiological Isotope Identification Device (RIID) is being promulgated with the next six months. Currently CG-721, DOL-44, nor the Maritime Law Enforcement Academy (MLEA) have discussed implementation processes for the RADSEEKER. This type of oversight could result in Radiation Detection Level II personnel the inability to determine the legitimacy of a radiological source. This poses a risk to national security and the safety of Coast Guard personnel. As MLEA’s Radiation Course Managers there needs to be an effective formulated plan of creating training material, integrating training material to academy staff, and procedures for members in the fleet to become proficient.
In certain respects, the Violence Against Women Act (VAWA) is indeed workable and achieves some of its intended goals. VAWA was originally designed to make communities and homes safer for women, as well as to protect women’s civil rights. According to Modi, Palmer, and Armstrong (2014), since the implementation of VAWA in 1994, the rate of domestic violence directed towards women declined by 53% between 1993 and 2008. The overall estimated number of victims of intimate partner violence in the U.S dropped immensely, from 2.4 million in 1994 to 907,000 in 2010 (Modi, Palmer & Armstrong, 2014).
The average annual radiation dose received by Americans is 360 millirems (or "mrems"), about 300 of which come from naturally occurring sources like radon. By contrast, you would get only 0.01 mrems per year as a result of living 50 feet from a nuclear power plant. Even a single annual cross-country airplane flight exposes you to 3 mrems, while a medical X-ray gives you a dose of 20 mrems.
Ionizing radiation is a form of radiation that can alter the structure of DNA molecules in living cells. It is a kind of energy produced by atoms that travels in form of electromagnetic waves. Sources of this form of energy are x-ray
Radioactivity is when energy is emitted from the nucleus due to the nucleus being unstable. The 3 types of radiation are Alpha ,Beta and gamma. Alpha particles have 2 protons and two neutrons. Examples of radioactive nuclei that emit alpha radiation. Are : uranium, thorium, actinium, and radium They are very ionising so they give energy off onto whatever they are in contact with. Therefore, it loses energy more quickly. They are not very penetrating so can be stopped by a piece of paper or skin. Beta particles have 1
Radiation is one of the main forms of energy (Pettigrew 1). In today’s environment we are only familiar with the basic types of radiation. These types are in the form of
On old radios the antenna was detrimental to the radio’s operation. Today, the antenna is not necessary. AM radio does not have as good of quality as FM but it can travel farther distances. FM signals can be interfered by things such as mountains or other barrier
While healthy babies are born every day, not everyone is so fortunate. In many cases, diagnostic radiology is required for patients during their childhood. Can having this radiation during the formative years lead to adverse effects later in life? The biggest concern from radiation is the risk of cancer. Cancer can occur at any dose from ionizing radiation because it is a stochastic effect, meaning that it is probabilistic. The probability of a stochastic effect, such as cancer, increases as the dose increases. While receiving this radiation may be necessary, it can cause some serious trouble later in life, such as breast cancer, leukemia, and thyroid cancer.
In an effort to address the issue of radio frequency radiation exposure in this community, we will provide a background on the sources of radio frequency radiation as well as the known and suspected health effects. We will also proposed two epidemiological studies and discuss risk management and
Job and his friends were not aware that his (Job) suffering was inflicted by the devil who sought permission from the Lord to test the faithfulness of Job towards God. After Job suffered the loss of all his children and possession as well as well as being afflicted with sores all over his body, his friends Zophar, Bildad and Eliphaz sought to find meaning as to why all this occurrences. They tried to explain that it was because of sin that God punished man; this being a key argument of the law as written in Deuteronomy 28, wisdom literature in Psalms 37; 92; Proverbs 10:27-30 and Old Testament prophecies and that this could have been the case with Job. On the other hand, Job who had a strong belief on the justice of God accused God of injustice in the sense that He (God) was not adhering to his own rule considering Job believed that he has been faithful to God and has been careful to avoid any kind of evil.
In 1985, a Canadian-built radiation treatment device began obliterating holes through patients’ bodies. The Therac-25, designed and developed by AECL (Atomic Energy Canadian Limited) was an advanced linear accelerator that could speed up electrons turning them into a high-energy beam that annihilated surface tumours on the skin, or could converted the electrons into x-rays to penetrate tumours deeper within the body. The Therac-25 was the latest and greatest version of the French company’s previous models, the Therac-6 and Therac-20. One million dollars were invested into this machine to give radiation treatments to cancer patients. Most of the patients receiving treatment from the Therac-25 had already endured a form of surgery to remove the majority of the tumour and were using the Therac-25 as a means of eliminating any leftover growth. This high powered radiation machine was controlled by a computer from a separate room to protect the operator from being exposed to any unnecessary, moreover unwanted, doses of radiation.
radiation (the kind used in X-rays) is known to cause cancer at high doses, the risks of
