A museum conservation laboratory studies a preserved animal specimen containing bones surrounded by soft tissue. Staff need to produce an image of the bones without cutting open the specimen. The laboratory also prepares sampling tools that must be sterilised after they have been sealed in transport packs.
Explain which type of electromagnetic radiation should be used to show the bones without cutting open the specimen.
Explain which type of electromagnetic radiation should be used to sterilise the sealed sampling tools.
State one way staff can reduce their exposure to the radiations used in (a) and (b).
