The direct-reading pocket dosimeter is a portable instrument designed to measure the total accumulated dose of moderate and high levels of gamma radiation. The instruments make use of a small quartz fiber electroscope as an exposure detector and indicator. An image of the fiber is projected onto a film scale and viewed through the eyepiece lens. The scale is calibrated in roentgens (R) and may be read by looking through the eyepiece toward a lamp or other source of light. A CD V-750 zeroing unit must be used in conjunction with the dosimeter to set the instrument to zero.
