When Uranium-235 is bombarded with a single neutron, the following fission reaction occurs: Find x, y and z. 235 U + n → 141Ba +38/Kr + zn 92 X 56 36- x = 92, y = 1, z = 3 x = 93, y = 1, z = 3 x = 92, y = 0, z = 3 x = 93, y = 0, z = 2
Tectinium - 99m -
Technetium-99m is used to image the skeleton and heart muscle in particular, but also for brain, thyroid, lungs, liver, spleen, kidney, gall bladder, bone marrow, salivary and lachrymal glands, heart blood pool, infection and numerous specialized medical studies.
Radium - 226 -
Radium needles and other forms were implanted into cancerous tumors to arrest the cancerous growth.
Iodin -131 -
iodine is used to treat overactive thyroid, iodine deficiency, and to protect the thyroid gland from the effects of radiation from radioactive forms of iodine.
Chromium -51 -
Chromium 51 is used for the labeling of red blood cells for the evaluation of mass or volume, survival time and sequestration studies, and for the diagnosis of gastrointestinal bleeding. But
human studies have clearly established that inhaled chromium (VI) is a human carcinogen, resulting in an increased risk of lung cancer.
Therefore
Chromium -51 will not be commonly used in medical field.
