LEGISLATION
Current legislation (Radiation Protection Act) dates from 1965Several deficiencies when compared with Basic Safety Standards and GS-R-1New legislation has been drafted and is going through machinery of governmentMay pass onto Parliamentary Agenda in 2005 or 2006
National Radiation Laboratory
TRANSPORT, WASTE SAFETY & EMERGENCY REGULATIONS
Transport requirements established in radiation safety legislation (adopting ST-1)Waste safety & emergency regulations invoked through Codes of Safe Practice as condition of licence15 Codes in use; 8 under developmentProposed new Act will directly empower Codes

TRANSPORT SAFETY
NRL is national competent authorityST-1 enacted into law (2000)NRL maintains oversight of national transport emergency response planNRL is responsible for border control, documentation, and packagingNRL holds regular training programmes for carriers, port & airport personnel, central agencies
National Radiation Laboratory
EMERGENCY RESPONSE
NRL maintains the multi-agency response plan, including radiological terrorismAgencies include hospitals, fire, police, defence, health protection officers, civil defence (and Department of Prime Minister)Licensees expected to manage low level emergencies, especially where there is no risk to publicHealth Protection Officers (30 nationally) provide first point of call responseHPOs trained, equipped by NRL NRL provides high level response including waste management, remediation & health physics oversight
