| IONIZING RADIATION CONTROL PROCEDURE AND MANUAL |
1. SCOPE
This practice includes the following major sections:
- General Requirements
- Procedure/Manual Contents
- Radiography
2. APPLICATION
This practice applies to work activities and employees under the control of [YOUR COMPANY] and its contractors.
3. DEFINITIONS
Gamma Radiation – High frequency, high energy electromagnetic radiation that is highly penetrating and may be detected after passing through several inches of steel.
Ionizing Radiation – The emission of atomic particles or electromagnetic radiation from the nucleus of an atom.
Non-Ionizing Radiation – Electromagnetic radiation includes ultraviolet, microwave, and radiofrequency radiation, lasers, and infrared.
NORM – Naturally Occurring Radioactive Materials located in rock and soil formations throughout the earth’s crust. NORM is found in many oil and gas streams and may move with these streams as they are extracted and transported. NORM may be found on vessel walls, piping, pump casings, and other process equipment.
Survey – An evaluation of the radiation hazards related to the production, use, release, disposal, or presence of radioactive materials or other sources of radiation under a specific set of conditions. When appropriate, such evaluation includes a physical survey of the location of materials and equipment, and measurements of levels of radiation or concentrations of radioactive material present.
4. GENERAL REQUIREMENTS
4.1. Qualified Person
An individual who meets the definition of a Qualified Person and is so designated in accordance with Work Practice (HSE General Requirements) will prepare, or oversee the preparation of, a site-/project-specific procedure/manual.
4.2. Regulations
Local, state, federal, and in‑country standards must be thoroughly reviewed so that applicable and appropriate requirements are identified and incorporated into the site/project‑specific procedure/manual.
4.3. Exposure to Airborne Radioactive Material
[YOUR COMPANY] and its contractors/lower-tier contractors must not possess, use, or transport radioactive material in such a manner as to cause any employee to be exposed to airborne radioactive material in an average concentration more than regulatory limits.
4.4. Personal Monitoring
[YOUR COMPANY] and its contractors/lower-tier contractors will make such surveys as may be necessary to comply with applicable regulations.
[YOUR COMPANY] and its contractors/lower-tier contractors will supply appropriate personnel monitoring equipment such as film badges, pocket chambers, pocket dosimeters, or film rings, and will require the use of such equipment.
4.5. Caution Signs, Labels, and Signals
Symbols prescribed by applicable regulations must use the conventional radiation caution colours (magenta or purple on yellow background).
Each radiation area must be conspicuously posted with a sign or signs bearing the radiation caution symbol described in applicable regulations.
4.6. Immediate Evacuation Warning Signal
The signal-generating system will be designed to incorporate components that enable the system to produce the desired signal as prescribed in applicable regulations each time it is activated within a one-half second of activation.
Initial tests, inspections, and checks of the signal-generating system must be made to verify that the fabrication and installation were made in accordance with design plans and specifications and to develop a thorough knowledge of the performance of the system and all components under normal and hostile conditions.
Once the system has been placed in service and following significant alterations or revisions, periodic tests, inspections, and checks must be made to minimize the possibility of malfunction.
4.7. Notification of Incidents
[YOUR COMPANY] must immediately notify the entity designated in applicable regulations by telephone or telegraph of any incident involving radiation that may have caused or threatens to cause:
Exposure of the whole body of any individual to more than allowable limits
The release of radioactive material in concentrations exceeding allowable limits
In addition to any notification required above, [YOUR COMPANY] will make a report in writing in accordance with applicable regulations.
