A compilation of microdosimetry for uniformly distributed Auger emitters used in medicine
Bibliographic record
Abstract
PURPOSE: To provide a compilation of microdosimetric characteristics for 12 Auger emitters commonly used in medicine. MATERIALS AND METHODS: Monte Carlo electron track structure simulations are performed for 12 Auger emitters. They are (55)Fe, (67)Ga, (99m)Tc, (111)In, (113m)In, (115m)In, (123)I, (125)I, (193m)Pt, (195m)Pt, (201)Tl, and (203)Pb. Proximity functions of 12 Auger emitters are calculated from the simulated track structures and compared with that of gamma rays from (60)Co. RESULTS: Some of those Auger emitters are highly radiotoxic compared to hard gamma rays from (60)Co. The more electrons per decay and the lower electron energies, the more effective an Auger emitter could be. CONCLUSIONS: The high radiotoxicity of Auger emitters is due to correlations of low-energy electrons released from decay processes. If these correlations were disregarded, Auger emitters would not differ significantly from other low linear energy transfer (LET) radiation sources. Even in the case of uniform distribution, some of those Auger emitters are highly radiotoxic compared to hard gamma rays. For Auger emitters to bond to radiosensitive sites in cell nucleus, much higher radiation effectiveness could be expected.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
