Question

Problem 3 Superman has just recieved 1.7 Sy of radiation over his entire body from alpha particles (RBE = 12) (A) If Superman's mass is 100 kg, how much energy did he receive from this dose? (B) Captain Marvel has a mass of 75 kg. How many grays would she receive if she absorbed the same amount of energy over her body? (C) How many Sy would she receive if the damage was caused by beta particles (RBE 1.5)? By heavy ions (RBE = 20)?

Answer 1

Pa 4 А) A: SУ - 4.7 Joule received вие? Superman's mass is 100 *, He received 4.7*100 = 470 Joule of Олег . B) Captain Monored acceined Регт гел а 414 -Б > 6. 21 Sy AS RB EE12 • 27 6. 21 Sу — 0:52 2. Same energy г 4то Joule г sy . 1

( then If RBE -115 ( foro beta particles) she would receive 0.52x115 = 0.78 sy. A DA RBE = 20 (fom heavy ions) Sibiri the she would receive 0.52x20 = 10.4 sy, co
