All of the above Check - ANS The correct answer is: A and B only The NRC or State Inspector blows a puff of smoke under the closed door in the room in which 133Xe ventilation studies are performed. What is the purpose of this test, what should happen to the puff of smoke, and is the test still mandatory? a. The ...

Gas Ventilation - ANS Xe 133, 81 KeV, 5.3 half life; reactor produced dose: 10-20 mCi imaging: posterior position negative pressure room required uses activated charcoal trap to accumulate the exhaled xenon gas until decayed to background single breath: during inhalation wash in / equilibrium : collected while the xenon distributes through aerated portions of the lung wash out : while radioactivity is cleared from lungs Sr 89 Chloride - ANS Strontium Chloride, Metas...

D. is correct. Minimizing the amount of time spent in a radioactive area, increasing the distance from a radiation source, and using a shielding material such as lead, are three practical methods for reducing exposure from radiation. - ANS 1) The three most important factors to be considered when handling radioactive materials are: A. activity, distance, type of emission B. organ sensitivity, type of emission, distance C. type of emission, shielding, area of exposure D. time of ex...

Which Statement about the half-life of a radionuclide is correct? A) It is the time it takes for the radioactive source to become stable B) It is half the time it takes for an atom to decay C) It is half the time it takes the activity of the source to decrease to zero D) It is the time it takes the activity of the source to decrease by half - ANS D) It is the time it takes the activity of the source to decrease by half What does the x - axis in the following graph represent? ...

A false positive In-111 WBC scan may be due to increased abdominal uptake in a patient: a. that is currently taking antibiotics b. with a sinus infection c. with a stomach ulcer d. with a renal cyst e. with cholecystitis - ANS B.

Calculate the 24 hour percent uptake using the given data: Dose Count= 1425916 cpm Background= 88 cpm Patient counts= 193046 cpm Patient Backgrou...

allow 10-15 minutes for tracer localization standard views are anterior/posterior, left lateral, right lateral, RAO, LAO, RPO,LPO an anterior view with the costal marker and a 10 cm and 5 cm marker are used to see the size or the organs SPECT may also be used What percentage of sulfur colloid localizes in the liver and spleen? - ANS 85% in liver and 10% in spleen the remainder goes to the bone marrow What is a known variation in size of the liver? - ANS R...

radiopharmaceuticals - ANS nuclear medicine is a medical specialty that focuses on the use of radioactive materials called function - ANS NM studies determine the cause of a medical problem based on organ or tissue injection, swallowing or inhalation - ANS in a NM test the radioactive material or tracer is generally introduced into the body by gamma or scintillation camera - ANS what is used to transform these emissions into images that provide in...
