你的医学或物理化学常识都有误!又让人笑了!
“铊”恐怕不属于放射性物质,以讹传讹就不好了!

None of the thallium ordinarily found in nature is radioactive. Like all elements, there are synthetic radioactive isotopes of thallium.
Thallium Stress Test ( basic knowledge for medical professionals)
This is a type of nuclear scanning test or myocardial perfusion imaging test. It shows how well blood flows to the heart muscle. It's usually done along with an exercise stress test on a treadmill or bicycle.
The thallium stress test is useful to determine:
When the patient reaches his or her maximum level of exercise, a small amount of a radioactive substance called thallium is injected into the bloodstream. Then the patient lies down on a special table under a camera ("gamma camera") that can see the thallium and make pictures. The thallium mixes with the blood in the bloodstream and heart's arteries and enters heart muscle cells. If a part of the heart muscle doesn't receive a normal blood supply, less than a normal amount of thallium will be in those heart muscle cells.
The first pictures are made shortly after the exercise test and show blood flow to the heart during exercise. The heart is "stressed" during the exercise test — thus the name "stress test." The patient then lies quietly for 2-3 hours and another series of pictures is made. These show blood flow to the heart muscle during rest.
What does the thallium stress test show?
你一个自称具有医学硕士学位,并在美国开业的人,居然弄出如此之大的洋相。你已经不是第一次出医学之丑了。使人不得不怀疑你的情况的真实性。
