Convert Disintegrations per minute to Rutherfords
Convert Disintegrations per minute (dpm) to Rutherfords (Rd) instantly and accurately.
Conversion Formula
Rd = dpm × 1.666666667e-8
About Disintegrations per minute
The disintegration per minute (dpm) equals exactly 1/60 Bq ≈ 16.7 mBq. Standard output unit of liquid scintillation counters (LSC) in biochemical and biomedical research for ³H and ¹⁴C tracer assays; radioimmunoassay protocols report results in dpm/well. 1 dpm = 1/60 Bq = 60 dph.
About Rutherfords
The rutherford (Rd) equals exactly 10⁶ Bq = 1 MBq. Proposed by Ernest Rutherford and adopted at the 1946 Montreal Conference on Radioactivity as a convenient unit for large sources. Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
