Rod Source Replacement
In this section we will describe the replacement of rod sources on
shieldings with the following ID no:
– Type 80
– Type 100
– Type 120
– Type 150
– Type 200
– Type 270
Radioactive sources may be replaced only by competent and
licensed persons, taking into account official regulations.
Health hazards due to radiation!
When replacing a source, you have to work with the unshielded
source for a short time. An increased dose of radiation is harmful to
health.
You have to carry a pocket dosimeter during work to measure the
personal dose and to document the actual radiation exposure.
Moreover, work has to be coordinated with the competent Radiation
Safety Manager.
IMPORTANT
For Germany you have to keep in mind:
Source replacement by the customer is possible only if:
1) the appropriate technical qualification is guaranteed
2) the work to be done to replace the source has been approved
explicitly by the regulatory authority. Your “License to Handle
Radioactive Substances” states whether you are in possession of
such a license.
Prerequisite for this work is detailed knowledge of the design of the
shielding; appropriate drawings must therefore be available.
