An effective treatment for some cancerous tumors involves irradiation with "fast" neutrons. The neutrons from one treatment source have an average velocity of 3.1 ×10^7 m / s . If the velocities of individual neutrons are known to within 2 % of this value, what is the uncertainty in the position of one of them? | Numerade

A person exposed to fast neutrons receives a radiation dose of 200 rem on part of his hand, affecting 25 g of tissue. The RBE of these neutrons is 10 . (a) How many rad did he receive? (b) How many joules of energy did this person receive? (c) Suppose the person received the same rad dosage, but from beta rays with an RBE of 1.0 instead of neutrons. How many rem would he have received? | Numerade

Liquid metal fast reactors use fast moving 🏃 neutrons that could allow them to operate on both fissile material and used fuel from current reactors to produce electricity⚡️. ➡️ This could greatly reduce the amount of spent fuel required for permanent disposal. ➡️ The reactors use liquid metals such as sodium or lead as a coolant and operate at higher temps and lower pressures than current reactors for increased efficiencies and enhanced safety performance.
