Information session on aircrew exposure to cosmic radiation

Brussels, January 20th 2009A. Fremout, FANC

Radiation Protection Landscape of Public Services

involved The Federal Agency for Nuclear Control (FANC) centralises the

competences in radiation protection and nuclear safetyMission : “Protection of the public, the workers and the

environment against the hazards of ionizing radiation”

However, many interactions exist with other Public Services:

• Internal Affairs (Crisis Centre of the federal government)

• FPS Employment, Labour and Social Concertation :– Occupational Health and protection of workers in general

• FPS Public Health, Food Chain and Environment : – Medical professions– Public Health– Social Security– Medicines and medical devices

…

General radiation protection measures

General regulation for radiation protection in Belgium : R.D. of July 20th, 2001 ( http://www.fanc.fgov.be)

- art. 20: limitation of the doses -

Art. 20.1.1: the 3 general principles of radiation protection :– Justification– Optimisation (ALARA – as low as reasonably achievable)– Dose limits

Dose limits• Occupationally exposed persons

– Effective dose: 20 mSv per 12 consecutive months– Inhomogenous irradiation of individual organ of tissue : specific limits

• Students– > 18 years? Limits for occupationally exposed persons– 16 years < x < 18 years?

• Effective dose: 6 mSv per year • Inhomogenous irradiation of individual organ of tissue : specific limits

– < 16 years? Limits for the public

• Public– Effective dose: 1 mSv per year– Inhomogenous irradiation of individual organ of tissue : specific limits

• Protection during pregnancy and breast feeding– Working with non-sealed sources during pregnancy and breast feeding not allowed– When there is only external radiation : the unborn child (“public”) should not run the

risk to exceed 1mSv during pregnancy.

! DOSE LIMIT ≠ DOSE CREDIT !! ALARA !

Dose limits specific aircrew

• Exposure of air crew to cosmic radiation should be monitored or estimated

• When the risk exists that the dose limit for the public is exceeded : specific protection measures– Determine the individual dose due to cosmic radiation– Take the dose estimation into account when establishing

the work schemes– Inform the workers involved of the health risks– Female workers : protection of the unborn child

Protection measures- art. 27 and following -

Manager of undertaking (= operator) is legally bound to put protection devices and dosemeter(s) at disposal of his workers

Aviation : • Head of the undertaking is responsible for the dosimetry• Dosemeters not appropriate• Calculate/estimate the dose by means of simulation

• Protection devices/measures: – Protection by distance– Protection by shielding– Protection by limitation of the exposure time (working schedule !)– Prevention of contamination

Basic objective : Ensure in an efficient way the radiological protection of both permanently employed and outside workers.
