Radiation units

  • J. Craig Robertson


It is clearly important to have some understanding of the units which are used in radiation protection. The instruments which are discussed in chapter 8 all have a dial or scale which is graduated in terms of one or other of these units, and in order to make proper use of these instruments it is necessary to understand what any particular reading on the scale means. One of the most frequently used units is the rem. This was used in chapter 1 when the concept of maximum permissible dose was discussed, and was also used when the annual dose to each individual from the natural background was given. The other two units which are most frequently used are the roentgen and the rad. Use is also made of rad/h, rem/h or roentgen/h to describe the rate at which radiation is received.
