T w o systems are available ( 1 ) a continuous scanning arrangement that yields a strip chart recording of radio activity that you can lay alongside the c h r o m a t o g r a m and (2) a stepwise scanning arrangement that gives you a printed record of count and time information corresponding t o the radiation m e a s u r e m e n t of succes sive areas, each equal to the slit opening.
