Question Answer
At low energy (issues)Resolution lost due to difficulty locating gamma hit in crystal
At high energy (issues)Resolution lost due to collimating difficulties
Low energy energiesupto-200 keV
Medium energy energies200-300 keV
High Energy energies360-500 keV
Ultrahigh Energy energies511 keV
