Selected methods for estimating radiation dose.
| Dosimetry . | Method . | Utility . |
|---|---|---|
| Biological | Whole-body counting | Not generally available, impractical. |
| Chromosomal aberrations (dicentrics, ring forms) | The “gold standard.” Typically requires 4–5 days processing time. | |
| Lymphocyte depletion kinetics | Inexpensive but requires 2–4 days for decline at doses of 4–6 Gy and 4–6 days at 2–4 Gy | |
| Interphase aberrations (PCC, okadaic acid/kinase) | Under development | |
| Electron spin resonance (dental enamel) | Permanent record of exposure but requires removal of tooth | |
| Clinical | Symptoms and signs | Practical but loses sensitivity at low doses. |
