Health Physics Radiation Conversion Tools Suite
A toolkit for medical/nuclear/radiation workers and students.
Absorbed Dose
Convert between SI (Gy, mGy, μGy) and traditional (rad, mrad, μrad) units. 1 Gy = 100 rad.
Sievert to Rem
Convert between SI (Sv, mSv, μSv) and traditional (rem, mrem, μrem). 1 Sv = 100 rem.
Radiation Exposure
Convert between SI (C/kg, etc) and Roentgen. 1 R = 2.58 × 10⁻⁴ C/kg.
Radioactivity (Activity)
Convert between SI (Bq, kBq, MBq, GBq) and Ci, mCi, μCi, nCi, pCi. 1 Ci = 3.7 × 10¹⁰ Bq.
Energy
Convert between Joule, eV, keV, and MeV. 1 eV = 1.60218 × 10⁻¹⁹ J.
Radon Exposure: WL, WLM ↔ MeV/L, J/m³
Convert between Working Levels (WL), Working Level Months (WLM), MeV/L (classic), and SI units (J/m³, J·h/m³). 1 WL = 1.3×10⁵ MeV/L = 2.08×10⁻⁵ J/m³.
Frequency to Wavelength Converter (Nonionizing)
Converts EM wave frequency (Hz/MHz/GHz) and wavelength (m/cm/mm/nm): λ = c/f, where c = 2.998 × 10⁸ m/s.
Linear Interpolation Calculator
Finds y for a given x along the straight line from (x₀, y₀) to (x₁, y₁).
