Radiation

Foods are exposed to a specific dose of radiation which does not make the foods radioactive. There have been no sign of toxicology or safety issues by irradiating food products. Currently the Food and Drug Administration regulates food irradiation. Types of radiation, duration of exposure and dosage are highly regulated. Any foods that have been irradiated must contain the irradiation symbol on the package. When molecules absorb ionizing energy, they become reactive and form ions or free…

types have many leading causes, some of them being radiation, air pollution, and genetics. One cause of cancer is radiation. Most people think of radiation as nuclear bombs or cancer treatments. However, radiation takes many forms and is always around us. There are different types of radiation such as Gamma Rays, X-rays, Ultraviolet radiation, Radon, and cellular phones. All of these types have radiation along with having different amounts. Radiation is the release of energy from any source. It…

harmful ultraviolet (UV) radiation from the sun. Today the ozone layer is depleting due to the release of pollution containing chemicals chlorine and bromine. Such deterioration allows large amounts of UV B rays to reach Earth1 seen in figure 1, which can cause many harmful internal and external effects on humans. Although it has been proven that the depletion of the ozone layer has caused health issues, there are many other factors for these health issues. The UV radiation also allows humans to…

everywhere is several harmful effects that may destroy the life. Indeed, nuclear accidents and leaking radiations are worst issues that are involved in countries. The world has seen nuclear accidents and spread of nuclear radiation that have killed a lot of people who work on nuclear plants or live around plants. That happens mostly because the workers mistakes and the nuclear plants which control radiations to release energy steadily have their own defects. The Chernobyl nuclear energy plant…

years, how on earth are oncologists and scientists going to battle this problem? Today, many of those professionals turn to chemotherapy and radiation to battle the cancer, but is that the right choice? Everyone wants the solution to the problem, and since chemotherapy and radiation are the instant “go-to treatment”…

long-term and well-paid career. However, some of the doctors aspiring to be radiologist are scared away by the fact of the many risks associated with being a radiologist. Frequent exposure to radiations can cause cancerous disease especially if the doctor is not well protected. It does not matter how low the radiations are, but an accumulation of small amounts time after time is very hazardous to the body. However, attempting to get away with the risks associated with exposure is almost…

The harmful radiation in space is divided into two types, massive and massless radiation. Both can have high energy associated with them, Gamma rays are the most energetic form of massless radiation. When it comes to massive radiant the sun mostly emits protons with a scattering of alpha rays and betta rays. With proton emission having speed of nearly a…

5. 3. 4 Typical application and thermometric error Consider a typical application such as the measurement of surface temperature by a surface mounted thermocouple as shown in Figure 5.9 (a). Figure 5. 9 : (a) Surface mounted thermocouple in Example 5. 1 (b) Thermal resistance network model Heat loss from the thermocouple is modeled as shown above by discussion leading to Equation 5.3. Thermocouple attached to the surface of a massive solid whose temperature we would like to measure.…

cut off water. The water inside the exclusion zone has been contaminated by radiation and should not flow out of the area. Radiation is a source of energy that kills off animals when ingested or when animals come in contact in high amount of it. If contaminated water is kept from leaving the area, animals outside the zone are less likely to be affected. The only way to get rid of radiation is to let it settle. Radiation acts as a field similar to a magnetic field also know as a cloud. People and…

electromagnetic radiation. When an x-ray machine projects radiation onto the paintings, only the materials containing heavy elements absorb it. Radiation passes through the materials containing lighter elements. Unpainted canvas consists of three layers: the ground layer, the thread layer, and the priming layer. The ground layer is the bottom layer on which all other layers sit. There is nothing particularly important about the ground layer in painting, but it comes into play later on with the…
