Radioisotopes in Medicine Nuclear medicine uses radiation to provide diagnostic information about the functioning of a person’s specific organs‚ or to treat them. Diagnostic procedures are now routine. * Radiotherapy can be used to treat some medical conditions‚ especially cancer‚ using radiation to weaken or destroy particular targeted cells. * Tens of millions of nuclear medicine procedures are performed each year‚ and demand for radioisotopes is increasing rapidly.

that uses microwaves is radar. The radar uses microwave radiation to detect characteristics‚ range‚ speed of remote objects. Dangers That Have Been Reported: When injury from microwaves occur it usually results from insulated or stopped heating in the body. Exposure to microwave radiation can produce cataracts or clouding in the eye that destroys the passage of light and varies from slight to complete opacity. So exposure to microwave radiation can cause gradual blindness. One Scientist Associated

that all objects emit infrared radiation as long as the object is above absolute zero (Kelvins). The cameras that can see and distinguish temperature are called‚ “thermal imagers.” These imagers convert the perceived radiation into scaled colors relative to its temperature and create a different color per area. The basis to how these camera can see this radiation is that objects have blackbody radiation (Seffrin). Objects that can absorb light would also emit radiation (Rossing‚ 129). The emittance

Hospital for the day. Each of us were assigned to a new department to spend the day. I was assigned to the Radiation Oncology department. We went there to job shadow the nurses that work in our department. While job shadowing our goal is to follow the nurses and observe them giving basic care to patients. Upon arriving at Grand View Hospital I was feeling nervous with the thought of going to Radiation Oncology. I was nervous because I have

matter Q.1. State the dependence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of incident radiation is doubled‚ what changes occur in the stopping potential and photoelectric current? Q.2. How does the maximum kinetic energy of the emitted electrons vary with the work function? Q.3. the frequency of incident radiation is greater than the threshold frequency in a photocell. How will the stopping potential vary if frequency is increased‚ keeping other

Nuclear weapons cause unimaginable death and destruction. Without a doubt‚ these are the most powerful weapons mankind has ever built. However‚ there is also a scientific side to this weaponry which Teddy Roosevelt may have indeed called very big sticks. Nuclear weapons work by releasing the enormous amounts of energy that are contained in the bonds of atoms. The bonds of atoms can be broken in two ways. The first way is by fission‚ and the second way is by fusion. Fission works by the splitting

bomb testing around the equator. Even though it was a big step forward for the United States‚ when it comes to developing nuclear bombs. Consequently‚ the bomb testing resulted civilians to move from their hometown‚ furthermore left them exposed to radiation as a result causing them several unwanted diseases and genetic mutations. The worst part is at times‚ the civilians were left with no right to express their opinion nor feelings towards the bomb testing. That’s when Jane Dibblin a British journalist

the rays aren’t accurate and continue moving through the body until they exit‚ some of them are absorbed into surrounding healthy tissue. The most common areas of the body that are damaged by this type of radiation therapy is the bladder and other surrounding organs (Proton Therapy). Radiation itself is a known cause of cancer and this risk may outweigh the benefits for some when selecting a treatment option. Aside from potentially damaging normal functioning tissue‚ X-ray therapy causes minimal

involves the use of x-rays‚ a form of ionizing radiation‚ CT scan is used to detect and diagnose the presence and recurrence of tumors in human body and also provides the stage of a cancer. Several case studies have shown that CT scan can be effective in both colorectal cancer and lung cancer screening. Exposure to ionizing radiation is caused to increase the risk of cancer. Children may be at higher risk because usually children are more sensitive to radiation than adults and have a longer life expectancy

The surgery is followed up with RAI to completely eliminate metastasized thyroid cancer cells that remain within the patient’s body. External beam radiation is also used to treat or prevent the growth of follicular and Hurthle cell cancers in the neck area.
