The vertical distance between the open end of the source and the bench is 138 mm. A radiation detector, positioned vertically above the source, is attached to clamp T. A student is told not to move the stands closer together. 0 1 . 1 Describe a procedure for the student to find the value of d, the vertical distance between the open end of the source and the radiation detector. In your answer, annotate Figure 1 to show how a set-square can be used in this procedure. [2 marks] Question 1 continues on the next page 4 *04* IB/M/Jun21/7408/3A Do not write outside the box 0 1 . 2 Before the source was brought into the room, a background count Cb was recorded. Cb = 630 counts in 15 minutes With the source and detector in the positions shown in Figure 1, d = 530 mm. Separate counts C1, C2 and C3 are recorded. C1 = 90 counts in 100 s C2 = 117 counts in 100 s C3 = 102 counts in 100 s RC is the mean count rate corrected for background radiation. Show that when d = 530 mm, RC is about 0.3 s−1.
