Monitoring your radiation
3-4 NITON XL3 Analyzer User's Guide
Individuals can be monitored for the radiation dose they receive by use of
radiation dosimetry devices (dosimeters). Monitoring dose using a
exposure
dosimeter can be a way of identifying improper use and at the same time
demonstrating proper use. In some locations, dosimetry is required by
regulations and in others it is optional. It is normally required when the user
could reasonably be expected to receive in excess of 10% of the annual dose
limit. Thermo Fisher Scientific recommends that you determine and obey
the local regulatory requirements concerning radiation monitoring of
occupational workers.
Two common types of dosimeters are whole-body badges and ring badges.
Whole body badges are often attached to the user's torso (e.g., clipped to the
collar, shirt pocket, or waist as appropriate). A ring badge is worn on the
finger as a measure of maximum extremity dose. When worn, the specific
location of the dosimeter should be that part of the body that is expected to
receive the highest dose. This location will depend on how the analyzer is
used and so it may not be the same for all users. Dosimetry services are
offered by many companies. Two companies offering dosimetry services in
the USA and much of the world are:

Note Wearing a dosimeter badge does not protect you against radiation
exposure. A dosimeter badge only measures your exposure (at the dosimeter
location).
