The RTD Group NORM TRAINING: Increasing Awareness, Reducing Exposure Richard van Sonsbeek Röntgen Technische Dienst bv Dept. Radiation Protection Services P.O. Box AB Rotterdam The Netherlands Phone +31 (0) Fax: +31 (0)

The RTD Group Risks of NORM in O&G  Occupational exposure of workers (own personnel, or contractor personnel);  Contamination of the (local) environment;  Transfer of contaminated equipment and scrap metal to other companies, and possibly to other countries;  Liability;  Bad publicity  Workers have to be aware of these risks

The RTD Group Situation in the Netherlands  Most operators in the O&G industry have a license to perform work activities with NORM contaminated materials;  According to such a license operators have to appoint a radiation protection officer (RPO), either from own company, or hired from a consulting company;  Work activities are directly supervised by radiation experts, level 5 in case of routine jobs, and level 3 in case of non-routine jobs.  Workers have to be instructed on the radiation protection measures, and procedures (toolbox sessions);

The RTD Group Training in the Netherlands  Education on radiation protection is regulated (since the late 60’s);  Four levels of radiation expertise are described, ranging from level 5 (low) to level 2 (high);  Training institutes have to be recognised by the authorities (published in law gazette), and the authorities are represented in the examination boards

The RTD Group Extension of training in the Netherlands  The level 5 course consists of four days of theory, and one day of practical exercises;  Depending on the training institute, the level 3 course extents over a period of three to four months (not fulltime), and includes more practical exercises (university level);  All courses have to be completed by passing an exam.

The RTD Group New regulations in the Netherlands  Since Summer 2004 there is a specific NORM regulation (following implementation of Euratom BSS)  Listed identified industries have to investigate if they perform work activities, i.e. if they have a NORM problem  Depending on activity concentration work activities must either be reported or one has to apply for a license

The RTD Group Continuous training of radiation experts  Usually operators choose to have their own radiation experts level 5 to supervise routine NORM jobs;  (Of course) this is not a fulltime position;  Refreshing and keeping up with new developments is important, and therefore operators send their level 5 experts to refresher courses, e.g. provided by RTD;  Further the normal level 5 courses are very general, and not focussed on the problems in the O&G industry. The refresher courses aim to be more specific.

The RTD Group Radiation experts level 3  Radiation experts level 3 for supervision of non-routine jobs are usually hired from consulting companies, e.g. RTD;  For these experts keeping up with the latest developments is part of their job;  New experts are trained on the job, before they may act as supervising expert independently;  In the future a scheme of registration will be implemented in the Netherlands

The RTD Group NORM training in Africa

The RTD Group NORM problem at Operating Company in African country High radiation level at pipeline discovered by industrial radiographer. Results of NORM survey (RTD)  NORM contaminated installation parts;  NORM contamination of environment;  NORM contaminated scrap  Company has a NORM problem

The RTD Group How can the company deal with this NORM problem?  There are no national laws & regulations on ionising radiation, let alone law enforcement in the country where it is operating;  There is no infrastructure with regard to: -radiation protection; -decontamination facilities; -radioactive waste treatment and disposal

The RTD Group Short term solution  Compliance with Group regulations on radiation protection (what, if these do not exist?)  Drawing up procedures based on these regulation  Training of workers to implement the procedures  Proper storage of contaminated materials, and radioactive waste

The RTD Group Long term solution?  Guidance is necessary by international body (IAEA) on issues like: -Practical radiation protection measures; -Limits (harmonisation); -Training of personnel; -Disposal options for NORM waste; (IAEA Safety Report Series No. 34, 2003)  International harmonisation would be desirable because NORM is a world-wide problem (and not only in O&G industry)

The RTD Group Implementation of Group regulations  Policy statement with regard to NORM;  Limits (dose (rates), activity concentration);  Organisation (Radiation Protection Advisors, -Supervisors, and - Technicians);  Qualification of personnel (Training);  Measurement and sampling program

The RTD Group NORM training  Creating awareness for risks of NORM;  Diffusion of awareness through the whole company and into the local society;  Implementation of measurement program;  Re-assurance of ignorant workers  Protection of workers, environment, local public, and in the end the World population;

The RTD Group Students  Mixed population with regard to education and work experience;  Most of students have no background in Physics, let alone Radiation Physics;  Not all students speak English;  We make a distinction in the training for RPS, and the training for RPT

The RTD Group Radiation Protection Supervisor  Inspect and supervise NORM jobs;  Quality Assurance of radiation protection;  Organise monitoring and sampling;  Radioactive waste qualification;  Proper packaging, storage, and disposal Two or three day training (depending on availability of students)

The RTD Group Radiation Protection Technician  Measure contamination levels;  Register and report results;  Notify RPS if count rates exceed limits;  Supervise routine NORM jobs One or one and a half day course (depending on availability of students)

The RTD Group Theoretical part

The RTD Group General theory  Basic atomic and nuclear physics;  Ionising radiation ( , ,  );  Interaction of ionising radiation with matter;  Biological effects;  Dose and dose rate, annual limits;  External exposure, internal contamination All at an introductory level, you need it to discuss it in order to explain other issues

The RTD Group Focussed theory  Origin of NORM in oil and gas production. Where can you expect to find it?;  Detection of NORM (use of portable monitors);  Interpretation of measurements;  Protective measures during NORM jobs  Company NORM procedures

The RTD Group Practical part

The RTD Group Measurements on location  Training is given “in house”;  During the training the students can perform measurements on their own workplace;  Students can directly ask questions concerning their own risks (re- assurance)

The RTD Group Advantages of NORM training  Motivated students (it concerns themselves);  “Bottom up” dissemination of awareness in company;  “Older” students can provide valuable historical information

The RTD Group Feedback  It is important that students are stimulated to actively participate;  Methods that can be used are: -Ask questions during training to verify is students understood what was said; -Start training with multiple choice “Test you knowledge” -Have a short exam at the end of the course, with an optional certificate

The RTD Group Thank you for your attention!
