|X-ray of a pair of feet|
The X-rays found in LHSA’s collections are a valuable source of information, however, the nature of their material composition means that they will, inevitably, degrade over time. As cellulose nitrate deteriorates it emits a strong odour, discolours to an amber colour, and becomes sticky and brittle.
