Pros And Cons Of Limiting Radiation

Each of the experiments used different dosimetry devices to detect the amount of radiation exposure. By using these devices not only does it measure how much radiation exposure patients are being exposed to but also the amount of radiation the technicians are being exposed to. Using different dosimeters helps predict which ones pick up more and less radiation. Dental radiology technicians should wear the dosimeter badges while working, so they can be measured at all times. By measuring the amount of scatter radiation in multiple ways helps us regulate the

Radiation therapy can be used anywhere in the body to treat any kind of cancer. Depending on what type of radiation therapy, it can have some side effects. The most common ones include fatigue, hair loss near the treated area, and skin darkening in the area exposed to a beam of radiation. ("Radiation Therapy for Cancer,” 1) There are also safety concerns that patients have when they are treated with radiation therapy. Many people that receive radiation therapy treatment, worry about exposing family and love ones to radiation, as well as the side effects. Radiation effects on the normal tissues are divided into acute and chronic effects (Schreiber). Acute effects occur during the course of therapy and during the post therapy period (approximately 2-3 weeks after the completion of a course of irradiation) (Schreiber).

There are pros and cons to daily usage and exposed to radiation. Radiation exposure to the bone

Nuclear medicine procedures utilize very small doses of short-lived isotopes (ones that only stay radioactive for a few hours or days), the amount of radiation received is generally less than or equal to that of an x-ray. Whole body and healthy tissue doses can be minimized while the radioisotope is targeted toward the affected tissue or organ. The isotope is then eliminated by the body through the urine or fecal matter.

There are two reactions that happen in the human body when ionizing radiation within the diagnostic range (30-150 kilovolt peak) is

Beginning with the accident at Three Mile Island in 1979, a widespread belief has proliferated that all levels of ionizing radiation are dangerous. Since 1980, radiation hormesis studies have shown there is actually a threshold of danger with high level exposures, but below that threshold low dose radiation is essentially safe and quite possibly beneficial to life. Yet, this relatively new, seemingly contradictory understanding of radiation's health effects has gone essentially unknown to the general public. In order to grasp the reasons why, we must again return to the bombing of Hiroshima and Nagasaki.

Ira Helfand demonstrates ethos, or authority, to argue the fact that any amount of radiation can be detrimental to public health, no matter how small. In order to effectively represent authority with this claim, Helfand uses a report from the National Research BEIR VI, “It is the consensus of the medical and scientific community, summarized in the National Research Council BEIR VII report, that there is no safe level of radiation,” (Helfand, 2012. Para. 2). The National Research Council BEIR VII specializes in the study of nuclear energy. For this group to insist that there is not an amount of exposure to radiation that could be deemed as safe, it is more of an “eye-opener” on the argument. Consequently, including an expert organization’s findings into his article allows Dr. Helfand a security of authority on the

This note is very important, because radiation is a very dangerous thing and you have to make sure you know the steps and for what you’re doing. Never take a risk.

Due to the risks that can occur from high radiation levels, a backup plan has been developed in the case of high radiation levels. To start, at the start of the project a Geiger Counter will be purchased in order to keep track of all the radiation and determine whether the radiation ever reaches unsafe levels.

According to the video, effects attributed to radiations will still occur even after several centuries and the radiations are considered to be causative agents for dangerous incurable diseases such as cancer. As per the video, the best measures for one to protect himself or herself from nuclear fallout and radiation are distance, shielding and time. Therefore, it is useful for one to adopt some protective measures even if they are temporary. It is suggested that the more shielding, distance and time an individual takes, the better

The maximum permissible exposure for a person under 18 working with radiation is one-tenth the adult limit or not to exceed 500 millirems per year above the 300+ millirems of natural sources, plus medical radiation. This was established in 1957 and reviewed as recently as 1990. Like alcohol intoxication levels, levels of exposure to radioactivity (due to radioactivity deposited in the body) depend on a person's weight. A diagnostic tracer of one microcurie of radioactive calcium 45, given orally, would result in an exposure of 3.7 millirems for a 100-pound person, and half of that, 1.85 millirems, for a 200-pound person.

Metal manufacturers, to obtain the proper thickness of tin and aluminum Highly sensitive gauges to measure the thickness and density of many materials use radioisotopes quality of steel is also checked by guages. Construction crews also use it, to gauge the density of road surfaces and subsurface. Pipeline companies, to look for defects in welds and use as tracers to pinpoint leaks in piping. Several countries have implemented nuclear water desalination, including India, Japan and Kazakhstan. Nuclear-energy-powered water desalination is a well-understood technology, with thousands of man-hours behind it.Science Studies Carbon-14, a naturally occurring, long-lived radioactive substance, allows archaeologists to determine when artifacts containing plant or animal material were alive, created or used.Radioactive carbon dating allows us to observe data of earth.Agriculture aspect of it all is that radiation can Increase shelf life and preserves food, 40 plus Countries have approved of using radiation to help preserve foods, also uses irradiation (exposing object to radiation) it kills bacteria, More than 10 species of insects have been eliminated by radiation insects, and parasites which these could have caused food borne illnesses. NEI states “Food irradiation does not make the food radioactive, and it does not change the food any more than canning or freezing.” also radiation Develops more disease resistant

For example, the monitoring device and accompanying tools will easily detect the movements of breathing and account for it during radiation treatment. However, uncontrolled movements inevitably will result in undesired circumstances. If the subject encounters a cough attack, the entire body shifts due to the forced compression and expansion of the lungs. This can dangerously move the subject’s radiation target area, and so the laser tape measure can be calibrated to perform an emergency shutdown of the treatment to ensure the safety of the subject. This threshold can be set by the technician or physician attending the subject. Also, subjects undergoing radiation treatments might feel nervousness or anxiety. This can cause the subject to shake or breathe abnormally, which can also endanger them. These factors can be dealt with by the emergency shutdown, and the treatment can resume when the attendant sees that the subject’s safety is

Before any type of shielding needs to be discussed, the fact of timing needs to be brought up. The Sun periodically creates solar flares that produce very large pockets of energy. These solar flares can be predicted pretty well, and if they are known (approximately) when they are going to happen, a mission can be dictated when would be the best time to go. If you go when there is the best possible radiation environment in solar system, then you reduce the requirements and strain on the devices that are blocking the radiation. Also something to consider is the Forbush decrease. When the Sun produces a coronal mass ejection, it sends out a huge wave of particles into the solar

The use of radioactive elements in medicine is still growing to this day. Many oncologists use it to treat their patients who have cancer. Many cancer patients use this option. They use the radiation to kill off cancer cells. X-ray technicians or radiologists will also use it to administer x-rays to people who may have a broken bone, or need an MRI. The patient is injected with a radioactive material that helps the doctor be able to see inside the body better, whether it be with pictures or ultrasound. Radioactive material is defined as “material that contains radioactivity and thus emits ionizing radiation. It may be material that contains natural radioactivity from the environment or a material that may have been made radioactive.” (The Healthy Physics Society). This happens when someone needs a colonoscopy. They have to drink or are injected with this liquid that helps their organs and all other masses in the body be seen better by the radioactive materials.
