    I've had technetium-99 for a medical test. It was one of the scariest tests I've ever been through and I'm someone who used to pass out when getting my blood drawn because I had such a severe needle phobia. I got to the room for the test and two technicians began swathing me in protective clothing covering every inch of skin from the neck down with a lead blanket underneath. I had to put on two pairs of medical gloves and then a pair of really thick mitts which were taped closed, then one tech went into another room and came out in a full body suit carrying my radioactive breakfast. I just looked at them and said, "I'm supposed to EAT this stuff?!" Afterwards I was told to stay away from pregnant people for the next 24 hours because I was too radioactive to be near a fetus.

      ​@@0verv0ltage I know, but no one explained that to me at the time so it was scarier than it needed to be. It's not completely insignificant to the patient though if spending a short time time near a pregnant person afterwards would be enough to potentially damage a fetus.
      A single nuclear imaging study _does_ increase your risk of cancer, although it's a small increased risk for an individual test, but medical radiation has a cumulative effect and every doctor acts like they're the only one who has ever ordered one of the riskier tests/procedures for a patient (nuclear imaging test, CT scan, fluoroscopy, panoramic dental x-ray.)

      Tc99 is not out of the question. You could pretty easily separate out some of it from the urine of a person who received a Tc99m treatment (contrary to what the video says, Tc99 has a half life of >200k years, Tc99m decays to Tc99 by gamma emission but Tc99 itself isn't super radioactive). The quantity in the urine will be only about 10ng, though. Americium 241 (about 1 microgram) can be obtained from an ionizing smoke alarm.

    This is *heaven* for me! I LOVE working with and handling radioactive materials! Each isotope has its own unique energy spectrum or "fingerprint" and branching ratios. I have some relatively strong Am-241 sources that overflow my detectors and have made the vials foggy and discolored. Am-243 gives off 74.5 keV gamma rays at about 68% and 43 keV at about 6%. Also, it alpha decays to the extremely radioactive Np-239 which has a 23 hour half-life. Pu-239 gives off many gamma ray energies, but all of the gamma rays are much less than 0.1% per decay. Most other gamma energies emitted are only a millionth of a percent! The most common gamma from Pu-239 is 51.6 keV at only about 0.027%. Also, 800 mR/h? I have Radium-226 sources that are hotter than that! And they used a Ludlum gamma ray scintillation counter, which is an even more sensitive type of detector! It depends on the isotope. Odd numbered elements are usually more unstable than even numbered elements. Tc-99 is a weak beta emitter. And it has a long half-life of 211,000 years, not 20 years. So, it's not that dangerous, even chemically. The Cf-251 source was put in a drum surrounded by polyethylene or borated paraffin, which is to slow or capture neutrons. Also, it emits some gamma rays and a relatively high intensity of Cm-247 X-rays. Man, I'd _LOVE_ to work at ORNL! It's a shame that there's so much irrational fear attached to radioactivity, like these isotopes of these elements! Externally speaking, the dose from many of these aren't that dangerous, as long as you don't get the actual radioactive substance inside of you, since most of these isotopes are alpha emitters. Alpha is harmless externally. Because if more people understood radioactivity, we could own isotopes like these in exempt quantities without going through so much red tape! I could on and on about this!

      Radiation protection is all about distance, shielding, and time of exposure.

      @crashmancer 5 років тому +4

      I think what you’re asking is, can the radiation from one sample cause the other samples to react as well, like in a nuclear chain reaction? The answer is it depends on the sample and the kind of radiation. As people mentioned, alpha and beta particles don’t make it through glass. Neutrons might (and neutrons from plutonium banging into other plutonium so it emits more neutrons is how reactors work), but there isn’t enough material there to sustain that kind of chain reaction.
