Dose Pathways for uranium workers

• Internal Exposure to the lungs–

via inhalation of Rn‐222 gas and 

Rn‐222 progeny

• Internal Exposure to the lungs and  organs

via inhalation or ingestion of  airborne radioactive dust particles

• Long history of uranium mining in Australia• Radioactive ores first mined in Radium Hill, SA –

1906• Three currently operating uranium producing mines 

in Australia– Ranger– Olympic Dam– Beverley

• More in development– Honeymoon– Four Mile– Yeelirrie

National dose trend

Ranger Uranium mineSource: ERA Annual Report 2009

Australia follows the  worldwide trend of 

decreasing worker doses  due to improved 

occupational heath and  safety practices and 

radiation health  awareness.

Page 7: The australian national radiation dose register for uranium workers  guilfoyle

Exposure records for each worker shall be preserved during the worker's  working life and afterwards at least until the worker attains or

would have 

attained the age of 75 years, and for not less than 30 years after the  termination of the work involving occupational exposure.

IAEA, 1996, International Basic Safety Standards for Protection

against Ionizing Radiation and 

for the Safety of Radiation Sources, Safety Series 115, Appendix

1, Section 1.49.

International Best Practice

Records of doses assessed to have been received by an employee,including details of monitoring results and dose calculation methods, asrequired by the appropriate authority, shall be kept during the working life ofthe employee and afterwards for not less than 30 years after the

last dose

assessment and at least until the employee reaches, or would have reached,the age of 75 years.

ARPANSA, 2002, Recommendations for Limiting Exposure to Ionizing Radiation and National 

Standard for Limiting Occupational Exposure to Ionizing Radiation, republished March 2002 as 

Radiation Protection Series 1.

• How do we ensure compliance with national  and international best practice?

• How do we ensure records are maintained  and remain retrievable in the long term?

Adhering to international best practice standards

Australian National Radiation Dose Register is  designed to address these requirements for 

the uranium mining and milling industry in  Australia.

Background

MOU between RET  and ARPANSA for 

ARPANSA to   develop, 

construct and  implement a Register 

of uranium industry  worker doses

Page 10: The australian national radiation dose register for uranium workers  guilfoyle

• To record and track the lifetime radiation dose of workers  throughout their career in the uranium mining and milling  industry in Australia

• To provide assurance that dose records will be checked and  maintained, and remain retrievable, including when 

companies cease to operate

• To allow the production of annual statistics showing industry  sector trends and comparisons with international dose trends

• To answer requests from workers for the provision of  individual dose histories

• To notify regulators when an individual has exceeded their  annual dose limit

10

Objectives

Page 11: The australian national radiation dose register for uranium workers  guilfoyle

• ARPANSA chaired steering committee with  members from:

• The Australian uranium industry

• Worker unions

• Representatives from State and Territory regulators

• Representatives from the Department of Resources,  Energy and Tourism (RET)

• ARPANSA

Dose Data to be collected

Page 13: The australian national radiation dose register for uranium workers  guilfoyle

Worker personal information collected:

• the registered person’s name • date of birth • gender • employee number • place of employment • employee work classification • the period of time employed at a particular location• radiation dose

This personal information is only collected to distinguish one individual  from another and will not be used for any other purpose.

Personal data to be collected

Page 14: The australian national radiation dose register for uranium workers  guilfoyle

• Limited amount of security cleared staff  allowed access to data

• ARPANSA Information Technology Security  Policies

• Privacy Act 1988• Internal policies and procedures• Only individual workers can request their 

radiation dose history

Dose History Report

• Quarterly  Radiation Dose

•Annual Total Dose

•Rolling Five Year  Average Annual 

Dose

Page 18: The australian national radiation dose register for uranium workers  guilfoyle

• ANRDR ready to accept worker’s radiation doses  from July 1, 2010

• ANRDR will soon be ready to accept and process  requests from workers for their radiation dose 

history

• Currently holds data from South Australian  uranium mining operators, represents approx. 

85% of current workers

• Information will be available on the ARPANSA  webpage for operators and workers

18

Operational Status of the ANRDR

Page 19: The australian national radiation dose register for uranium workers  guilfoyle

• Distinguishing workers– Links to be created between suspected workers and checked– Information collected on worker includes: name, birth date, 

gender, and employee number

• Dose reporting frequency– Quarterly dose reporting, allowing for all quarters to be reported 

annually

• Currently no legislative requirements for mines  to provide doses to the register

– A different approach is required for each State and Territory.  In  SA, data submission from a mine operator to the ANRDR is now a 

licence condition.  Still unresolved in NT, but progressing. 19

Issues That Have Arisen

Page 20: The australian national radiation dose register for uranium workers  guilfoyle

• Worker awareness program

• Site visits

• Fact sheets

• Newsletters

• Look forward to working with industry and  unions to strengthen awareness

• Expansion to other states and territories

• Expansion of ANRDR to include ARPANSA staff  dose records

20

The future...

I will be available at Morning Tea for  demonstration of the web portal operation and 

for further questions
