Safety Legislation Flashcards
why is there need for legislation
risks come with xrays
exposure is 1.5days or less of natural background radiation exposure
ALARP meaning
as low as reasonable practicable
must be justified
dose limits
3 basic principles of radiological protection
justified = benefit outweights detriment
optimised = ALARP
limited = limits to ensure no unacceptable level of exposure
IRR17 [ionising radiations regulations]
who - staff and public
controlled areas with rules
risk assessments used to evaluate
control area 1.5m from xray beam tube
employer and employee responsible
IRMER 17 [ionising radiation medical exposure regulations]
who - medical exposures of pts and others
must be optimised and justified
- insufficient info requests sent back, balance exposure, risk, benefit
staff must be trained and entitled
loves ones can help but need to know risk
IRMER17 roles
referrer = sufficient data for practitioner to justify
practitioner = justification, ensure dose ALARP
operator suitably trained, limit dose
