Where can radiation accidents occur?
 During operations at facilities where these radioactive sources are used, examined or stored;
 Unauthorized access due to inadequate or absence of security;
 Transportation

Consequences of Radiological accidents
 Health consequences e.g Death, loss of limbs, burns, 
increased risk of stochastic effects (cancers)
 Environmental contamination
 Social & Economic consequences

 

Factors Contributing to Accidents
(a) Failure to follow radiation Protection Procedure

(b) Inadequate Radiation Protection Program

(c) Equipment failure

(d) Equipment failure

(e) Failure to use a survey meter or failure to use it properly

Examples of potential accidents
 melting of the gauge and source
 accidental loss of source during well logging
 lost or stolen source
 physical damage to the gauge
 jammed shutter
 transport accident
 suspected exposure of persons
 leaking source
 Source Jam
