30. Name at least one individual in history whose life was most likely lost or shortened due to exposure to radiation and briefly describe the type of exposure that was most likely the cause of the life threatening radiation damage.
Homework Answers
In 2013 November 7 former Palastin leader Yasser Arafat was dead in case of radiation Poisoning. He was found to had 18 times the normal level of Polonium in his rib, pelvis and soil stained with his decaying organs and detected that he was poisoned. These dangers due to the radiation is not known in early days. The radiation Poisoning is rare but are deadly.
Polonium-210 (P-210) is a high energy alpha emitter. It have a radioactive half-life of 138 days. It become hazardous once it is ingested, because of the low range of alpha particles in the human biological tissues. As a result of this external contamination does not cause radiation sickness. But if taken internally the poison becomes fatal within a month. This information is conveyed in journal or radiological protection. Polonium effect is named as acute radiation syndrome where the patient first shows the symptoms like nausea, vomiting, anorexia and diarrhoea. After this phase patient experience hair loss and bone marrow failure. The patient may die within weeks or a month.

. HISTORY: A 29-year old Caucasian female presented at clinic with a new onset of bilateral ankle pain. Symptoms started after she began a running program consisting of 3 miles on Tuesday, Thursday and Sunday two weeks prior. Her pain level has progressed from mild to severe. She had not previously engaged in regular exercise. She described her pain as achy, an “7” on a 10-point pain scale, and mostly in the medial ankles. The pain was made worse with walking and minimized at...
