Phisical Properties
Iodine-125 has a half-life of 59.4 days and decays due to the electron capture by the release of characteristic photons and electrons.
The major photon emissions are 27.2 keV, 27.5 keV, 31.0 keV and 35.5 keV with an average energy of 28.5 keV.
Table 1 indicates the decay chart of I-125 seeds.
Titanium tube properties: Grade 1 (It is not classified as implant class, as it will remain in the body for less than 29 days)
Tumor Marking Needle: 7 cm, 10 cm, 12 cm and 15 cm in length (should be selected according to breast type and size).
Needle Stopper: It is the barrier placed between the stylet and the tumor marking needle in order to prevent the I-125 seed source
placed in the tumor marking needle from unintentionally leaving the tumor marking needle

With a thin lead film, the dose rate can be decreased by 99.9%. (0.25 mm or 0.01 inch). Less dosage exposure to healthcare personnel and patients is ensured when used with I-125 preservatives. I-125 seed sources can be used only by individuals trained in the safe use and handling of radioisotopes by a competent government authority.
Direct contact with I-125 seed sources should be prevented. The use of tweezers is recommended. While operating with sources, appropriate measures should be taken. Personnel monitoring is needed. For the monitoring of hand and whole body exposure, dose measuring instruments such as personal dosimeters should be used. All practical measures should be taken during the preparation stage and during the implantation of the source to ensure that exposure is kept relatively low. Measures such as reducing exposure time, increasing distances, proper preparation of administrative procedures and the use of preservatives should be considered in order to maintain the target time.
