Given the organic nature of the human body, special steps must be taken to halt the deterioration process and maintain the integrity of the remains in their existing state. [2] These types of museum artifacts have great merit as tools for education and scientific research, yet also have unique challenges from a cultural and ethical standpoint.
Chemical hair analysis is used for the detection of many therapeutic drugs and recreational drugs, including cocaine, heroin, benzodiazepines and amphetamines. [3] [4] Hair analysis is less invasive than a blood test, if not quite as universally applicable. In this context, it has been reliably used to determine compliance with therapeutic drug ...
The original difference was that radiography fixed still images on film, whereas fluoroscopy provided live moving pictures that were not stored.

[1] Due to this, trace evidence is often overlooked, and investigators must be trained to detect it. [1]
