ISO Calibration Phantoms

• Comply with the standard ISO 4037 part 3¹
• Represent parts of human bodies regarding back-scattering of the incident radiation
• Suitable for calibrations and type tests of personal dosimeters, because they measure the quantities
• H_p(0.07) and H_p(10)

The ISO calibration phantoms comply with the standard ISO 4037 part 3¹ which describes standard test phantoms for calibration and type tests of personal dosemeters, that measure the dose quantities H_p(0.07) and H_p(10). The phantom composition is acrylic material (PMMA). Three types representing parts of human bodies in regard to back-scattering of incident radiation are available:

• Slab phantom: The water slab phantom represents the human torso and consists of a 300 mm x 300 mm x 150 mm cube, which is filled with water. The front wall is 2.5 mm thick; all other walls are 10 mm thick.
• Pillar phantom: The water pillar phantom represents a lower arm or leg and consists of a circular cylinder with 73 mm diameter and 300 mm length, which is filled with water. The wall is 2.5 mm thick; the bottom and cover plates are each 10 mm thick.
• Rod phantom: The acrylic rod phantom represents a finger and consists of a circular acrylic cylinder with 19 mm diameter and 300 mm length.
