Public Health Problem : Light Coming From The Sun

Radiation exposure during pregnancy has been debated by health practitioners for a while now. According to the researches carried out it can be concluded that radiation exposure especially to pregnant females poses a threat to the fetus in the formation stage and also later in life. Although pregnant women are advised not to expose themselves to radiation, it may be difficult due to background radiation in the environment that comes from radioactive substances in water, food, air, construction materials and soil.

This kind of exposure is likely from not taking the correct protective measures when being around higher levels of radiation. The effects from chronic exposure can be after you have had and acute exposure as well. This would be where radioactive material has tried to have been fixed. Some longer lasting effects of being exposed to higher levels of radiation is differents types of cancer. Some of the types of cancer consist of leukaemia, bone cancer, thyroid cancer, and lung cancer. Sometimes even genetic effects like some malformations in children born to parents exposed to radiation. Not every child born from parents who have been exposed will have malformations but they have a higher chance. This can also go for animals as

One well-known, historical disaster that came about as our world entered the Nuclear age, was the Chernobyl accident of 1986. Although in this situation nuclear technology had a negative effect on society, other revelations surfaced that have a positive effect on society. Nuclear radiation technology has allowed for a new way of diagnosing and treating patients to be possible. This process begins by injecting a radioactive substance into a patient. The substance serves as a radiotracer that self-distributes itself throughout the body and collects in damaged areas. The patient is then taken into a camera that allows radioactivity to supply an image. The first time through provides an X-ray image and the second time through provides a PET scan. The combination of these two images provides a PET/CT image. This image clearly illustrates where the diseased areas are located in the patients body, allowing for doctors to conclude a more accurate diagnosis for the patient. Once the patient has been diagnosed, depending on the situation radiation therapy can be used as a form of

Trends of monitored, exposed radiation workers, collective doses, annual average dose, exposed annual average dose of medical, industry and research during the year 1999 to 2008 are discussed in detail.

Can be traced back to experiments made soon after the discovery of x-rays (1895), when it was shown that exposure to radiation produced cutaneous burns. The use of radiation continues today as a treatment for cancer in radiation therapy. Henri Becquerel discovered after multiple experiments that it was the material itself that gave off the rays. Later on Marie Curie named it radioactivity. She found out the elements which are thorium, polonium, and radium. Radiation was really helpful during World War 1. During that time, people found out that radiation materials that are high can be extremely dangerous. People can die because of radiation, because of radiation exposure. That was proven with, “Radium Girls”. In 1993, it provided a wealth of information on the long-term effect of radiation exposure. The case also provoked drastic changes in both the fields of workplace safety & liability, and the field of Health Physics, dealing with the health effects and safety issues involved in working with radioactive materials. The Manhattan Project that had a bomb involved, led to the long-term radiation exposure.

Ionizing radiation that is used in medical imaging releases free radicals. These radicals can interfere with the molecular chemical bonds that is responsible for regulating the cellular function inside the cell. The interaction between free radicals and the molecules inside the cell might lead to genetic mutations in the DNA and it can damage cellular enzymes leading to the proliferation of cancer cells. In the United States, 50% of the environmental exposure to ionizing radiation is mainly attributed to medical imaging. Computed tomography (CT) scans are the main source of X-rays, a form of ionizing radiation. The purpose of this project is to present an overview of the main reasons for exposure, explaining the possible future effects of ionizing radiation on human health, enlightening the imaging modalities with ionizing radiation, addressing the population at risk, and explaining the main principles and recommendations to avoid and limit the exposure to ionizing radiation.

If a pediatric patient receives a lot of radiation then their cells could be mutated and reproduce causing more mutated cells. Pediatric patients in the 1940’s with respiratory problems would be diagnosed with their thymus gland being enlarged. The thymus reacts to infection by enlarging. Infants would soon have an enlarged thymus following birth and physicians would give the infants doses of x-radiation to reduce the size. Because the thyroid is by the thymus, it would also receive a dose. After 20 years, most of those people exposed would develop thyroid carcinomas. (Statkiewicz-Sherer, 1983)

The link between cancer and medically recommended x-rays has become more recognizable over the past decade or so. Involving the public in making them aware should be part of the responsibility of the physicians. distributing information of this magnitude will potentially save the lives of millions. People should be aware of the effects of having an over abundant amount of annual x-rays. These effects however, are only in the very extreme cases of server misuse of radiation or having an immense amount of x-rays taken over a long period of time. Studies recently done in the United States proves that over an extended period of time, the amount of radiation received from the x-rays causes the formation of mutated cells

Radiation effects are mostly to the skin and hair, but severe injuries can extend to the fat and muscle. There are several factors that can affect the severity of the injury and that is total dose which is the time between the radiation exposures and the size of the area being examined. Some other factors that could enhance patient injuries are smoking, obesity, and location of the skin being examined. The range of

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

Radiation is made up of subatomic particles that travel at 186,000 miles per second. Radiation can reach deep down inside the human body and create cancer. Radiation is a natural occurrence in our environment, and we are hit about 15,000 particles at all times. The chance of a particle of radiation penetrating your body is about one in 30 million billion, according to the Nuclear Energy Institute. A material is called radioactive when it actively emits radiation. There is no possible way for our body to tell if radiation comes from a natural source or not. The risk of getting a genetic disease from doses of radiation is lower than that of developing cancer from radiation. The risk of contracting cancer from radiation is about 0.002 percent. Levels of

This paper goes over radiation safety precautions and all the health risk dealing with radiation. I will discuss the discovery of radiation, non-iodizing and iodizing radiation, natural exposure to radiation, Alpha, Beta, and Gamma radiation and how they affect us. Also the paper will be going over radiation from human activities: underground miners, radiologists, medical

Long-lasting effects are much more common.Continuing effects result from fairly low-level exposures over an along period of time. They develop relatively slowly. The main long-lasting health effect of radiation is cancer. When taken inside beta emitters can cause tissue mutilation and increase the risk of cancer. The risk of cancer growths with increasing of the dose.Gamma’s piercing power and ability to travel great distances, it is considered to be the hazard to the human.

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).

“Although radiation may cause cancer at high doses and high dose rates, public health data do not absolutely establish the occurrence of cancer following exposure to low doses and dose rates — below about 10,000 mrem (100 mSv). Studies of occupational workers who are chronically exposed to low levels of radiation above normal background have shown no adverse biological effects. Even so, the radiation protection community conservatively assumes
