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
Medalia (2011) concludes that ionizing radiation, in other words radiation separate from harmless radio waves and light, has the ability to knock electrons out of atoms, causing a condition that produces an electrically charged atom that can damage human cells. Only a very small amount is needed to produce biological change. Symptoms include cancer, genetic mutations, sickness, vomiting, diarrhea, hemorrhaging, and at high doses, death within hours (Medalia 2011).
The process where food is exposed from nuclear sources consists of food irradiation, which is limited to high-energy gamma rays, X-rays and accelerated electrons. Ionizing is source of radiation because of the high-energy free electrons from atoms and molecules. The electrically charged particles are converted to ions. Microwaves are example of gamma rays. Accelerated electrons can transfuse to treat the food only to a depth of three centimeters. Due to thickness of x-rays may pass through the food.
The mission of EPA’s Radiation Protection Program is to protect human health and the environment from unnecessary exposure to radiation. This page provides basic information about the health effects of radiation. EPA uses current scientific understanding of the health effects of radiation exposure to create protective standards and guidance. Ionizing radiationHelpIonizing
When people think of radiation they immediately think of the worst case of radiation poisoning. Some people don’t even realize that there is radiation all around us. We use radiation waves for our microwave and cell phones. Doctors use radiation in X-rays and MRI’s. There are different levels of radiation.
Radiation therapy uses Ionizing radiation, this radiation passes through tissue forming ions. Bushong says that ionizing radiation can remove an electron from
o Description of the type of radiation it produces Iodine 131 emits Beta and Gamma radiation. Beta radiation consists of electrons and its penetrating power is very low whereas Gamma
Sterilising- Gamma rays which are high energy electromagnetic waves that can only be stopped by thick lead, this means they can pass through medical equipment because they aren’t made of lead, such as syringes. When gamma rays pass through packaging they inactivate viruses and kill bacteria. If the equipment stays in a sealed plastic bag it will remain sterile.
Cesium 137. These two particles emit both Gamma particle radiation and also Alpha particle Lee 4 radiation, as these radioactive elements were the by-product from the Fukushima nuclear power plant. Emphasized by the World Nuclear Association, a singular dosage rate of a micro Sievert is
The human body is made up of approximately 80% water (H2O) molecules. When radiation strikes a water molecule it causes radiolysis. Radiolysis is the disassociation of water into an ion pair (H+ and OH-) and two free radicals (H* and OH*). Free radicals are highly reactive, unstable and capable of disrupting bonds and causing deoxyribonucleic (DNA) damage. DNA is the molecule that holds the genetic information needed for cell duplication and is considered the target molecule for radiobiology. Ionization is the removal of an orbiting electron from an atom. There are two effects of ionizing radiation on a cell: indirect and direct. Direct action occurs when DNA is hit by ionizing radiation. Indirect action occurs when free radicals transfer
Advantages and Disadvantages Using Gamma Rays in a Clinical Manner The radiation of the gamma ray can be pinpointed in any part of the body, not harming or causing unwanted side effects to other parts of the body. The normal cells around the designated area are harmed, but can usually easily repair themselves. However, since the rays interact with your
Fukushima Radioactive Nuclear Leak Over the years Fukushima has had a radioactive leak that has been affecting the water and air through many towns. March 11th 2011, Fukushima had a earthquake that followed up with a tsunami, the tsunami shorted out the power of many nuclear reactors resulting in a leak.
Of course there are other ways that cancer can occur. For example, chemicals and The radiation that is used can be powerful to damage the DNA that is in the cells of the body. Radiation can cause more mutations in the body, aside from those that are already present in the cells, these mutations can also be passed down towards more future generations. It can also cause unbalance in cell. The energy from the radiation travels to the body tissue, this can cause cell damage or cell death. In some cases there are no effects but in other cases the cell becomes abnormal and has mutations. This happens when the tissue of the body has absorbed a lot of energy. There is no answer for which is more common, environmental or genetic. They both play a role in cancer, for example the gene can be genetically passed on with the mutation but it can be prevented. Although there are the environmental factors that can cause that mutation to keep on growing in the life of the person who has it. The mutation that is already in the gene can be disrupted and grow out of control causing
Beta rays: Beta particles have a negative charge which makes them same as electrons. The mass of beta particles is very small. The beta particles are deflected by electric and magnetic field.
Physics Essay There are three types of radiation – Alpha, Beta and Gamma. Alpha is 2 protons and 2 neutrons is the most ionising but the least penetrating. It is the most dangerous but is stopped by a few cm of air or a piece of paper. Beta is a high
