For calibration in medical emission tomography, the dosimeter and/or detector is calibrated in the field, such as at the clinic or other patient scanning location. To allow for a fewer number of calibration sources used in calibrating and/or assist in calibration for multispectral emission tomography, a calibration source includes multiple isotopes and/or a proxy source or isotope is used instead of the same isotope used in factory calibration.

A radiation dosimetry gel, usable in a polymer gel dosimeter having an improved sensitivity and high safety, includes a gelator, and a compound of the following Formula (1): ##STR00001##
wherein R.sup.1 is a hydrogen atom or a methyl group, m and n are each an integer of 2 to 4, k is 0 or 1, and a plurality of R.sup.1s and ms are each the same as or different from one another. Also provided for is a radiation dosimeter including the radiation dosimetry gel as a material for radiation dosimetry.

The present disclosure relates to a contact lens type dosimeter for measuring a dose distribution of a crystalline lens during radiation therapy, and a method of manufacturing the same. The ocular dosimeter has a contact lens shape and is configured to be worn on an eyeball, which comprises a basic material containing hydrophilic polyurethane, and a radiochromic dye. When the ocular dosimeter is worn on the eyeball, the dosimeter is configured to measure a radiation dose irradiated to a crystalline lens through a variation in color of the ocular dosimeter.
