خلي أشوف المهم

الي عنده الماده يدزلياها

اقروهه والباقي ع الله

بس هيه نفس الماده مامتغير شي

أسئله الفحوصات نهايه الكورس الاول دكتورنه جان دكتور محمد هسه تجيكم شهد

الاسئله هاي 👆الي دزيتهه هواي جاي منهه القراهن ضمن النجاح 🤝

سوو الي عليكم والباقي ع الله اتمنالكم كل التوفيق 🩷

اخوان هاي الاسئله اجت العام نصا بالحرف الواحد ومهمه واسئله واضحه

1 :B 2 : C 3 : B 4 : A 5 : C 6 : A 7 : B 8 : B

1. What are the three fundamental methods to reduce external radiation hazards?  • A. Time, Velocity, and Shielding. • B. Time, Distance, and Shielding.  • C. Density, Distance, and Time. • D. Shielding, Temperature, and Pressure. 2. Which formula is used to calculate the "Stay Time"?  • A. Stay~Time = Dose~Rate \times Limit • B. Stay~Time = Dose~Rate / Limit • C. Stay~Time = Limit / Dose~Rate  • D. Stay~Time = Time \times Dose 3. According to the Inverse Square Law, radiation intensity (I) is:  • A. Directly proportional to the distance squared. • B. Inversely proportional to the distance squared (I \propto 1/d^2).  • C. Inversely proportional to the distance. • D. Independent of the distance. 4. Alpha particles can be stopped by:  • A. A thin sheet of paper or a few centimeters of air.  • B. Several inches of lead. • C. Only thick concrete. • D. Aluminum or brass. 5. Why are low atomic number materials (like plastic or aluminum) used to shield Beta radiation?  • A. To stop Gamma rays more effectively. • B. To increase the speed of the particles. • C. To reduce bremsstrahlung radiation (secondary X-rays).  • D. Because they are the densest materials available. 6. The linear attenuation coefficient (\mu) is the sum of probabilities for which processes?  • A. Photoelectric Effect, Compton Effect, and Pair Production.  • B. Alpha, Beta, and Gamma decay. • C. Reflection, Refraction, and Scattering. • D. Fusion, Fission, and Attenuation. 7. What is the "Mean Free Path"?  • A. The total thickness of a lead shield. • B. The average distance a photon travels in an absorber before an interaction.  • C. The path taken by a radiation worker. • D. The inverse of the distance squared. 8. What is the recommended strategy when shielding multiple types of radiation (Beta and Gamma)?  • A. Shield the most penetrating type first. • B. Shield the less penetrating type first, then the more penetrating.  • C. Use lead for all types of radiation simultaneously. • D. Shielding is only required for Gamma radiation.
