Method | Source of information/ type of sample |
Sensitivity threshold |
Applicability | Reason for rejection |
---|---|---|---|---|
Analytical Dose Reconstruction (ADR) | Interrogation after exposure, witness confirmation | No threshold | Not universal | Applicable only for highly skilled ChNPP employees, tends to overestimate actual dose |
Electron paramagnetic resonance (EPR) dosimetry with teeth | Teeth extracted for medical reasons | 50 mGy | Not universal | Applicable only for tooth donors; useful dose range only partially matches liquidators' dose range |
Fluorescence in situ hybridization (FISH) | Blood samples | 250–300 mGy | Universal for living subjects | Useful dose range does not match the dose range for most liquidators |
Soft Expert Assessment Dosimetry (SEAD) | Interview | No threshold | Universal | Conceptually non-trivial, bad results of testing for some categories of liquidators |
