How Does Ionization Affect The Human Body?

Children are more susceptible to changes in their cells if given adult doses of radiation. Primary risks to

According to Ecker and Bramesco, the majority of the understanding of the effects of radiation comes from the research from the atomic bombings of the town of Hiroshima and Nagasaki (107). There is a greater effect when a dose of radiation is given all at once rather than over an extended period of time (105), However, as soon as radiation hits an individual there are some immediate effects and more long term effects. Some long issues that has come up due to the radiation of the atomic bomb were the more frequent cases of leukemia, cancer, and cataracts than people who weren’t affected from radiation (Ecker and Bramseco 107). Also, mutations can be a long term effect. Naturally, mutations occur at a low rate. Radiation can increase the number of mutation cases because it is a mutagen (Nasr and Hoyle). Some short term effects would be radiation sickness called acute somatic effects. Acute means severe and somatic means ‘related to the body’. The first signs of radiation sickness are nausea, throwing-up, and fever and

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

DNA can be damaged in two ways by radiation; directly broken by the radiation, or the radiation will ionize water molecules in the body and the free radical interacts with DNA strands and breaks them [1]. Even though repair is possible, it may be harder if both strands of the DNA are broken rather than just one, resulting in cell death or permanent damage to the DNA. Radiation is an important factor when planning for longer manned trips such as to Mars. Mars has no global magnetic field, and a very thin atmosphere so it cannot provide sufficient protection from radiation at the surface of the planet [2]. Earth’s multiple layers in its atmosphere blocks out most of the lethal forms of radiation.

Ionizing radiationHelpIonizing radiationRadiation with so much energy it can knock electrons out of atoms. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to cause chemical changes in cells and damage them. Some cells may die or become abnormal, either temporarily or permanently. By damaging the genetic material

Acute Radiation Syndrome occurs when someone is exposed to large levels of radiation. Within 24 hours a person generally feels nauseous with gastrointestinal ailments such as diarrhea. The radiation physically damages the DNA and cells within the bodies living tissues. Headaches and fevers occur. Large doses of radiation can quickly lead to death. Radiation burns can create permanent scarring or pigment disruption in the skin. In severe cases, the skin can be seared to the point that the damage is unable to be repaired and necrosis sets in. At times, it appears that the radiation exposure may have been minimal and the skin begins to heal, however, around 2 months later the skin will begin to necrotize leading to eventual, painful, death. The National Council on Radiation Protection & Measurements reports that, "radiation clearly induces mutations in microbes and somatic cells in rodents and

Ultraviolet (UV) light is an intermediate source of energy that can damage cells. The DNA in cells is especially sensitive to UV irradiation. The rings of the

Both the Chemical radiation as well as pathogens like bacteria, viruses or fungi can cause inflammation

Gamma radiation is weakly emitted from depleted uranium+ but the fact that internalized uranium has direct contact with cells within the human body is cause for concern. Gamma radiation is a mutagen, meaning that is causes incorrect replication of DNA within a cell. The incorrect replication in DNA occurs because the radiation causes free radical to develop within a cell that cause an incorrect order of nucleotides, and when the cell replicates so does the error. This continued replication of Incorrect cells can become malignant and cause cancer+. The human body is resilient and does eject the uranium from the body through

Acute radiation syndrome, or ARS, occurs in the whole human body when there are large doses of ionizing radiation strike for a short period. When an ionizing radiation occurs, it produces biologic damage inside the human body because the interaction within the cells causes molecular changes and inability to functions. It is a somatic effect that shows early symptoms of nausea, fatigue, and fever. Then months or years after radiation exposure, a person could potentially receive lung diseases, cataract, or cancer. These effects are examples of multiple epidemiologic cases involving human population that received high doses of ionizing radiation. This paper addresses one of the epidemiologic events that affected the Navajo miners handling a high

For most living organisms, humans included, radiation is considered dangerous if it has the ability to ionize other molecules, as this damages the cells and molecules critical to survival. On the surface of the Earth, humans tend to experience radiation in the forms of alpha, beta, or gamma particles (8), or through ultraviolet waves. An alpha particle is a helium nucleus, consisting of two protons and two neutrons, a beta particle is an electron, and gamma particles are high energy and high speed energy packets (8).

that the radiation can affect the water in a cell, if this happens then the cell of hydrogen

Every day patients are exposed to radiation with diagnostic x-rays, computed tomography, and radiation therapy. Exposure to radiation can cause biologic damage. Cellular damage can be produced by direct action or indirect action. Direct action occurs when the DNA is directly hit by a radiation photon, which can result in single-stranded breaks in DNA and two or more strand breaks. Indirect action occurs through the radiolysis of water leading to the production of free radicals. The hydroxyl radical and hydrogen radical are both unstable. The hydroxyl radical can result in the production of hydrogen peroxide, and the hydrogen radical in the presence of oxygen results in the production of the hydroperoxyl radical. Studies have been performed

The main source of radiation exposure to human life is Radon( 222Rn ) and its progeny which represent nearly 50% of the total human exposure to radiation from natural sources.222Rn is a radioactive gas producing from decay of Radium( 226Ra ) which is found in a wide variety of rocks, soil, natural gas and ground water. Most water sources in the earth’s crust have different levels of Radon concentration depend on the local geological characteristic of the source. Radon gas enters into the human body by inhalation and ingestion of drinking water and eating food, subsequently cause damage to sensitive cells of organs in the body ,such as respiratory and digestion systems.

beyond repair stop dividing or die off. Once the damaged cells die, they are broken down and the body eliminates them by the body 's natural processes. Radiation can damage normal cells as well.
