PART II SUMMARY OF PRODUCT CHARACTERISTICS 1 NAME OF THE MEDICINAL PRODUCT Sodium Iodide (l131) Capsule D. 2 QUALITATIVE AND QUANTITATIVE COMPOSITION Sodium Iodide (l131), with activity from 3.7 MBq/capsule at activity reference date and time. No carrier added. Contains per 37 MBq (1 mCi) of activity approximately 8 nanograms of iodine. Sodium Iodide (1 131), Capsule D is supplied as: 3.7 MBq/capsule at activity reference time 2.0 MBq/capsule 1 week after activity reference time 1.1 MBq/capsule 2 weeks after activity reference time 0.6 MBq/capsule 3 weeks after activity reference time Six colours identify the different strengths of the capsules. Every week, one batch is produced with one specific colour; this colour thus identifies both batch and strength. After six weeks, the colour first used is applied again. The six colours are: _Cap_ _Body_ White opaque White opaque Maroon opaque White opaque Green opaque White opaque Maroon opaque Maroon opaque Green opaque Maroon opaque Green opaque Green opaque Iodine-131 is produced by fission of uranium-235 or by neutron bombardment of stable tellurium in a nuclear reactor. Iodine-131 has a half-life of 8.04 days. It decays by emission of gamma radiations of 365 keV (81 %), 637 keV (7.3 %) and 284 keV (6.0%) and beta radiations of maximal energy of 606 keV to stable Xenon-131.

An estimation of the thyroid uptake and effective half-life obtained with a tracer amount can be used to calculate the activity required for radioiodine therapy. o In the management of thyroid carcinoma, sodium iodide is used to identify thyroid r Read the complete document
