Apples or Kiwis? Is 23Gy kidney absorbed-dose limit the way to go for radiopharmaceutical therapies?
Просмотров 698Год назад
Clinical trials for radiopharmaceutical therapies (RPTs) are usually limited to 23 Gray absorbed dose to kidneys. However, this value seems arbitrary when considering its source: a publication for external radiation beam therapy (EBRT) dating back to 1991, itself referring to a paper in 1968. The existing limit in fact neglects inherent differences between RPT and EBRT. In this episode, Nuclear...

    Answer to the question (19:35): The half-life for Re-188 is about 17 hours. After 10mins, more than 99% of initial activity still remains. So, we can assume the activity unchanged. Now we can easily multiply the activity by the sensitivity of collimator to obtain the total counts per second of Re-188: Total counts/sec = 10 MBq * 0.9 * 10^-4 = 900. Now we can calculate the number of 155 keV gamma rays counted per second which is 15.6% of the total counts: 900 * 15.6% = 140.4. If we continue counting for 10 mins, we will count a total of 140.4 * 10 * 60 = 84240 gamma rays with 155 keV of energy.

      @stephenber2114 Год назад

      from what i understand, c is the constant that represents the speed of light. so for E=mc^2, energy is equal to the mass of an object multiplied by the speed of light squared. in other words if you have a mass of something that is 1kg, then its energy is going to be 1 * the speed of light squared (alot of energy)

    How can you show that photoelectric effect is only possible if the electron is bound to an atom? (3:40) I’m confused😅

    • @omidgharibi4354
      @omidgharibi4354 7 месяцев назад

      A photon cannot give all its energy to an electron if its free. This is because of conservation of energy and momentum and the key point is that the photon wont exist anymore. Assume that the free electron is at rest before collision and the energy of the photon is less than 511 keV not to make a relativistic situation. If the photon gives all its energy to the electron, it wont exist after collision. Therefore, the total energy of the photon must be taken by the electron. => conservation of energy: Eph = 1/2 mv^2. Moreover, the momentum of the system must remain unchanged. => conservation of momentum: Eph/c = mv. By these two equations you will see that mvc = 1/2 mv^2 => v = 2c. We know that it is not possible for a particle to move faster than light. Now we understand why it is impossible to have a photoelectric effect if the electron is free. The same reason governs why in Compton scattering a photon cannot give all its energy to an electron.
