Pair production can occur when a photon with energy >1.022MeV passes near the nucleus and generates an electron and a positron #roedu #radonc #medphys #physics #photonweek

Photoelectric effect dominates @ diagnostic range; is proportional to Z^3. Happens when a photon hits an inner orbital electron ➡️ejects e-➡️ outer e- moves in to take its spot. Characteristic XR made; if hits e-, ejected as Auger e- #roedu #radonc #medphys #physics #photonweek

Compton effect dominates in the RT range and is independent of atomic number (unlike photoelectric and pair production). Photon hits e- ➡️ scattered photon & fast electron #roedu #radonc #medphys #physics #PhysicsEd #photonweek

Even very low radiation doses to the testes (0.15Gy) can cause reduced sperm count. 6Gy given all at once, or 2Gy spread out over weeks can cause permanent sterility. #roedu #radonc #radbio #radiology #fertility #oncofertility

Radiation exposure ➡️ ovarian dysfunction (sterility &⬇️endocrine function) @ low doses in older premenopausal pts (2Gy) and higher doses in prepubertal children (12Gy) #radonc #radbio #roedu #medphys #fertility #oncofertility #gyncsm #pedonc #hemeonc #medonc #oncology

Non-homologous end joining (NHEJ) is an error prone DNA repair mechanism involved in fixing double stranded breaks and making antibodies in the immune system via VDJ recombination #radbio #roedu #radonc #RTT #DNA

Thank you Bradford Hoppe for your incredible talk on the management of Hodgkin lymphoma today, and for requesting the creation of this graphic on Reed Sternberg cells! #HodgkinLymphoma #hemonc #pedonc #radonc #roedu CC: Bloodman Aaron Goodman - “Papa Heme” Mark Shapiro, MD Shematologist, MD

Can someone explain how this system merits the burden above? Ok, let's look at what is in store for a woman who, in light of this, doesn't want to shape her family planning around these exams. She suffers experiences like these.
