Dosimetry in thyroid follicles due to low-energy electrons of iodine using the Monte Carlo method

OBJECTIVE: To evaluate the absorbed dose in thyroid follicles due to low-energy electrons such as Auger and internal conversion electrons, besides beta particles, for iodine radioisotopes ( 131 I, 132 I, 133 I, 134 I and 135 I) utilizing the Monte Carlo method. MATERIALS AND METHODS: The dose calculation was performed at follicular level, simulating Auger, internal conversion electrons and beta particles, with the MCNP4C code. The follicles (colloid and follicular cells) were ...

Thyroid Cancer in Clinical Practice by I. Ross McDougall

The number of patients diagnosed with thyroid cancer is increasing dramaticallyin the United States, and there are more than 30,000 new cases annually.About 5% of adults have a thyroid nodule that can be felt and between 300/0and 500/0 have one or more nodules that can be identified by ultrasound.Thyroid Cancer in Clinical Practice covers all aspects of the diagnosis andtreatment of thyroid cancer. The author has spent more than 35 years inNuclear Medicine and Thyroidology in the clinical care o ...
