With a half-life of 60 days, a radioactive source would have lost half its energy in 60 days. Physicists and physicians use a decay table for determining the activity level on a given day. The radiation must transverse through healthy tissue to reach the cancerous area. Treatments are generally 5 days per week for 6-7 weeks. This differs from x-rays that provide a film of the image.
Fluoroscopy lights up extremely well for viewing radioactive seeds.
It is used during implantation and post implantation to view the placement and coverage of the seeds. Fluoroscopy views better than ultrasound. External reproductive organs. Relating to a gland. The reduced ability of the blood to clot.
