2. CHECK LIST
Job request and NDT procedure
Vehicle Pre-Start
Travel documents
Code and specifications
Equipment checked and calibrated
Calibration certificates ( if required )

3. ONSITE RADIOGRAPHY
Visually inspect the work area ( Look for doors / Opening /Rooms
into barricaded )
Do your JSEA before doing anything at site
Setting up barriers
Make a barrier plan
Keep monitoring the dose rate
Controlled area within 25μsv/hr.
Extend the barrier / use additional shielding if the controlled area is
more than 25μsv/hr.
Take 2 once the barrier is controlled
Look for non radiation workers during the onsite radiography
4. Define the boundary using warning signs and notices
Warning lights and audible alarm to be located adjacent
to exposure point
Ensure each source in use is properly separated and
barricaded and different monitors allocated
