Cock the plug at an angle so that the side of the

plug contacts the side of the dosimeter which will

insure a complete electrical connection (fig. 4).

Use only slight pressure to depress the dosimeter

charging pin; hold for about a second, which

should be sufficient to put a charge on the dosim-

eter. Be especially careful not to use radial

force that might bend or break the dosimeter

charging pin. It should be emphasized that

charging the dosimetcr by this emergency pro-

cedure is a delicate operation and extreme care

b. This emergency charger will put enough

charge on the dosimeter to leave the quartz fiber

in some position on the scale. The user should

note this position on the scale. Record this read-

ing in a note book. When the dosimeter is read

at a later time, the difference between the read-

ings will indicate the radiation dosage that the

user has been subjected to.
