An atom with an unstable nucleus is called a: Radio wave Radiopharmaceutical Radionuclide Radiochemical 2. Elements with same atomic number and different atomic mass number are called? Isotones Isotopes Isomers Isobars 3. The nucleus is composed of two types of particles called: Electrons and quarks Protons and electrons Neutrons and protons Quarks and protons 4. Dual time-point imaging (DTPI) can improve accuracy of positron emission tomography (PET) imaging. DTPI technique is a specialized protocol in which: Delay imaging is performed Flow study is performed followed by static imaging Dual-isotope technique is applied Two days delay imaging is performed 5. Which of the following is the half-life? Time taken for the number of radioactive nuclei to increase by a factor of two. Decay constant multiplied by the natural logarithm of two. Reciprocal of the decay constant. Time taken for the number of radioactive nuclei to decrease by a factor of two. 6. One of two or more different nuclides having the same mass number is called: Isotone Isotope Isobar Isomer 7. Which of the following is the principal decay mode of Tc-99m? Isomeric transition Electron capture Beta minus Pair production 8. Which of the following radionuclides has the highest kinetic energy of the positron? Rb-82. F-18. N-13. C-11. 9. An alpha particle is identical to the nucleus of a helium atom. Alpha particles: Are not charged Travel unlimited distances Are smaller than beta particles Are used for radionuclide therapy 10. Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting ionizing radiation. The emission is described as spontaneous meaning: The nucleus decays after collision with another particle or atom The nucleus decays after collision with shielding material The nucleus decays without collision with another particle or atom The nucleus decays without collision with shielding material 1 out of 10 Time's upTime is Up! بواسطة ناصر المطيري|2021-09-20T14:26:04+03:00أبريل 15th, 2021|معلومات عامة|لا توجد تعليقات شارك هذه الصفحة, واترك رأيك حول الموضوع باستخدام وسيلة التواصل التي تناسبك FacebookXLinkedInWhatsAppPinterestEmail عن: ناصر المطيري كبير أخصائيي الطب النووي في مستشفى حفر الباطن المركزي و مؤسس موقع نيوكليرمد. منشورات متعلقة اختبار: أساسيات الطب النووي اختبار: أساسيات الطب النووي أبريل 15th, 2021 | لا توجد تعليقات اختبار: رعاية المريض اختبار: رعاية المريض مارس 10th, 2021 | لا توجد تعليقات اختبار: الصيدلة النووية اختبار: الصيدلة النووية مارس 10th, 2021 | لا توجد تعليقات اختبار: الإختصارات والمصطلحات الطبية اختبار: الإختصارات والمصطلحات الطبية مارس 8th, 2021 | لا توجد تعليقات اترك تعليقاًCancel reply
