Gamma-ray burst

RESULTS AND DISCUSSION The ability of Pleurotus citrinopleatus and Aspergillus niger exposed to two doses of gamma irradiation (1 and 2 KGy) and immobilized on wheat straw to decolorize the dyes had been studied. Table 2 shows peaks of wavelengths of different types of dyes before and after decolorization. Peaks of reactive red 6 BX, direct brown BN, direct yellow 5 G, disperse orange 2RLS, disperse violet 3RS, sulpher black Br and sulpher brown SG were at 295, 240, 400, 444, 499, 220 and 250nm were

Agency), n.d.). There are several ways people are exposed to radiation, including x-rays, “radiation used to diagnose diseases and for cancer therapy,” nuclear explosive testing that goes wrong, “small quantities of radioactive materials released into the environment from coal and nuclear power plants,” etc. (IAEA (International Atomic Energy Agency), n.d.). The radiation that is emitted from cell phones, X-ray machines, and nuclear power plants are very different. They are all energy, but the difference

As I rotated through computed tomography (CT), I noted that radiologic technologists do not utilize in-plane shields as they do in radiography. Because shielding is emphasized so much in radiography, and because computed tomography is based on the same physics, I wondered why a technologist could not shield the areas that were not of interest. When I asked, some would say that they do not shield because streaking would show on the image and it would mess up their machine. Others told me that shields

warn against drawing conclusions about the impacts on sea life before peer-reviewed studies are completed. Secondly, gamma rays can be used in medical treatment to kill cancer cell. However gamma can be extremely dangerous because they are a very powerful source of power, if they delivered in an unmonitored and uncontrolled way they can kill humans, animals and plants. Gamma rays however can also disrupt the physical properties of materials. They can cause plastics and steel to become brittle and

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. Treatment- Radiation treatment is the most common therapy/treatment for cancer. Its users high energy particles such as X-rays to destroy

small intestine”. What does it have to do with nuclear medicine and radioactive elements? That’s a good question. It has to do with radioactive elements because the meal, liquid, or both are mixed with a little bit of radioactive material, than gamma rays are placed over the subjects stomach to track the amount of radioactivity that decreases in the stomach.  Gastric emptying studies use radioactive elements by using radioactive material.  What is a radioactive tracer? Another good question. That

care provider about changing or stopping your regular medicines. This is especially important if you are taking diabetes medicines or blood thinners. • Do not take any medicines that contain bismuth for 4 days before the scan. • Do not have X-rays that use barium contrast material for 4 days before the scan. • Do not wear metallic jewelry to the scan. • Do not drink very much for 4 hours before the scan. You will need to drink several glasses of water at the beginning of the scan. PROCEDURE

“Radiation Induced Dermatitis” Radiation Therapy is used to treat cancer in patients very comonly. Radiation Dermatitis is a common side effect from this treatment that ranges from mild rash to severe ulceration. It is also called radiodermatitis, x-ray dermatitis, radiation skin damage, or a radiation burn. According to Therapeutics in Dermatology radiation dermatitis was at one time considered to be a major problem in conventional radiography in the 1970s but now with the development of high energy

The Beta travels faster and penetrates further than any other. Gamma rays are the most dangerous from all since the can travel further and damage tissues and organs. Radiation can be measured in doses such as the Roentgens and the Rem. Radiation in our planet can come from cosmic radiation, terrestrial sources, the body

There has been a substantial amount of growth in dental radiograph technology and it has been accompanied by the potential for an increased dosage of ionizing radiation, but being able to utilize radiographs as a dentist is a necessity. Diagnostic imaging has been proven to aid the dental practitioner in diagnosing numerous oral diseases and problems. It has become apparent that ionizing radiation is a risk when acquiring dental radiographs, because the patient is exposed to ionizing radiation that
