IntroductionIntroductionIntroductionIntroduction Radiation protection and radiation safety:

Protection is “reactive” while “safety” is proactive and indicating positive gain.

Radiation cannot merely be controlled but preferably managed.

Management must not only be systematic but also systemic (i.e. System Management).

RSMS is a system approach to managing radiation hazards and risks.

RSMS involves the interaction of five major elements to achieve set goals.

The five major elements are: a. policy;

b. organizing;

c. planning and implementation;

d. evaluation; and

e. action for improvement

It is a written commitment of employer towards radiation safety at the work place.

A written radiation safety policy should be:

Should be specific to the organisation so as to indicate ownership;

May be written as a separate policy document or integrated with the company’s general OSH policy safety management system. The later is preferred because it ensures total safety management;




A written radiation safety policy should be:

Must be concisely and clearly written;States the radiation safety objectives;Set the safety standards that the organisation

subscribes;Is signed by the employer or the authoritative

manager; andDated.




Policy must be communicated to all employees.

Policy must be periodically reviewed for its relevancy.

Writing of a policy should have the contribution and participation of employees.

A policy will encourage self-regulation because both employer and employees know what is wanted of them through the written document.

This is the “WHO is suppose to do WHAT” element of the RSMS.

Organizing is about who will plan, implement and review such arrangements to achieve those targets.

Organisation needs to set up operational organisational hierarchy to help plan, implement and review all necessary arrangements in use.

Both individual and groups of workers contribute organising RSMS.

An emergency organisation is also part of the organisation managing radiation safety.

An emergency hierarchy organisation chain of command should be established for on-site emergency and/or off-site emergency.

Chain of command must be clear, in order to solicit fast and accurate response in the most efficient way.

The chain of command should be led by a person-in-charge/incident commander and supported by teams or/and individuals pertinent to emergency response.

Duties and responsibilities of all team and individuals in the emergency response team must be clearly defined.

Comprehensive planning must precede safe working practices.

Carry out initial review of the current radiation safety status and existing logistical support.

Initial review will: Look at what is currently in place and practice; Look at current compliance standards and practices;Assess current status in terms of performance standards; and Identify and recommend improvement measures to enhance

radiation and overall OS performance objectives and policy.



Cont …


PRFL and RPO in collaboration with radiation workers are responsible for the planning and implementations of radiation safety activities.

All planning and implementation should take into consideration set radiation safety objectives and safety policy.

One important aspect in planning and implementation of radiation safety management system is radiological hazards prevention. Two aspects of radiological hazards prevention are:

prevention and control measures; and management of change.




Prevention and Control MeasuresPrevention and Control Measures

Achieved through radiation risk management.

Radiation risk management involves:a. Radiation hazards identificationb. Radiation risk estimationc. Radiation risk evaluationd. Radiation risk controle. Radiation risk communicationf. Radiation risk control reviews


Radiation risk management is carried out for:Normal practiceEmergency or abnormal situations

Radiation risk assessment should be carried out:Before operationDuring operationAfter operation (decommissioning)

Radiation Risk ManagementRadiation Risk Management


Quantitative risk estimation based on measurement of potential dose exposure relative to maximum permissible dose limits.

Radiation Risk Management:Radiation Risk Estimation

Radiation Risk Management:Radiation Risk Estimation


Methods of identifying radiation includes:

SignagesCSDSRadiation detectors and dosimeters

Radiation Risk Management:Radiation Hazards IdentificationRadiation Risk Management:Radiation Hazards Identification


APPLICATION Annual Dose Limits (BSS)

I. Occupationa Exposure:

a) Annual dose limit for the whole body exposure of worker

b) Female pregnant worker: dose to the foetus accumulated over the period of time between confirmation of pregnancy and the date of

c) Partial body exposure of a worker:o Limit for the effective dose-equivalento Limit on equivalent dose for the skin (averaged over 1

cm2 of skin surface)o Limit on equivalent dose for the hands and feet

20 mSv

< 1 mSv

50 mSv500 mSv

150 mSv500 mSv

Annual Dose Limits as Recommended by the Basic Safety Standards



APPLICATION Annual Dose Limits (BSS)

I. Exposure of members of the Public

o Dose limit for whole body exposureo Equivalent dose limit for the lens shall not exceed o Average equivalent dose limit to the skin (averaged over any

1 cm2)o Effective dose limit for a person who knowingly assits in the

support of a patient during the period of diagnosticexamination or treatment of the patient

o Effective dose limit for a person below the age of 16 years visiting patient undergoing treatment or diagnostic examination involving radioactive material during the period of the treatment or examination of the patient

1 mSv15 mSv50 mSv

< 5 mSv

< 1 mSv




Risk evaluation is based on maximum permissible dose limits.

Evaluation in terms of levels of risks:Acceptable risk: risk that may be accepted without

any condition.Tolerable risk: risk that may be accepted with control

measures in place and the risk levels is tolerated. Intolerable risk: risk that cannot be accepted under

normal conditions.

Radiation Risk Management:Radiation Risk Evaluation

Radiation Risk Management:Radiation Risk Evaluation


Tolerable risk must be controlled and workers protected.

Two radiation protection systems: Proposed and continuing practices: these are actions which

cause exposures to radiation, Intervention: these are actions which decrease exposures

Three principles used in both radiation protection systems: Justification of practice Optimization of protection and safety Dose limit

Radiation Risk Management:Radiation Risk Control

Radiation Risk Management:Radiation Risk Control


All radiation risk should be communicated to radiation workers.

Important for employees to understand the radiation risk they are taking so that they know what control steps to be taken.

Use verbal and non verbal communications.

Radiation Risk Management:Radiation Risk CommunicationRadiation Risk Management:Radiation Risk Communication


There could never be a perfect assessment or control measures because radiation risk is not static.

Radiation risk control reviews ensure all preventive and control measures are still applicable and relevant.

Competent and authorized person to carry out risk communication.

Planning for emergency response and preparedness is required of ALL licensed organization.

Radiation Risk Management:Radiation Risk Control ReviewsRadiation Risk Management:Radiation Risk Control Reviews


Organization must: identify and categorize all types of emergency (radiological and non-

radiological emergencies); identify and categorize all types of accident situations; assess all related accidents and emergencies; consider the relevant radiological risk prevention arrangements; ensure all information with regards to emergency are communicated to

employees; consider arrangements to integrate organisational radiological emergency

response plan and preparedness (ERP) with in-house ERP and those ERP of relevant authorities;

ensure ERP skill training for all ERP personnel; and ensure that all arrangements are documented, and the documents are

maintained.



The most efficient way of controlling hazards is to control it at the source.

Incorporate safety consideration in: procurement and contracting.

EVALUATION

5 Elements of RSMSElement 4: EVALUATION



Performance of activities implemented must be evaluated.

Methods of evaluation, include: Performance monitoring; Accident investigation; Audit; and Management review.

Quantitative as well as qualitative method should be used in evaluation.




There are three ways in carrying out performance monitoring:

a. reactive monitoring;b. proactive monitoring; andc. active monitoring

Performance MonitoringPerformance Monitoring


A full accident investigation will help:

Identify the WHY and HOW of an investigation.

Identify the root causes of an accident. Identify corrective measures to prevent

the recurrence of similar accident.

Accident InvestigationAccident Investigation


Most effective method of evaluation is through management review.

The highest authority: Will be aware of the performance of their

radiation safety management system; and

Are involved in making major decision related to such performances.

Action for ImprovementAction for Improvement

The information gathered on weakness of the system and recommendation made should be implemented.

Anything implemented should be monitored for its success in correcting the weakness.

Continuous evaluation and improvement ensure continual improvement in radiation safety performance.


Continual ImprovementContinual Improvement

Continual improvement should be based on:a. justification of radiation technology used;b. optimization of the dose received to ALARA; and c. dose limit.

Fundamental commitment by management to proactively reduce radiation accident and ill health (effectiveness) and/or the system to achieve the desired aims by employing fewer resources (efficiency).
