## Decay Lab Description
DecayLab makes radionuclide decay calculations and radiation unit conversions quick and straightforward. Designed for nuclear medicine professionals, researchers, educators, and students, it provides a clean, focused workflow that works entirely offline.

Key features:
• Calculate radioactive decay for a wide range of radionuclides
• View activity at different reference and calculation times
• Apply decay corrections quickly and consistently
• Work with Bq, kBq, MBq, GBq and TBq, alongside nCi, µCi, mCi and Ci
• Convert absorbed dose in Gy and rad, and equivalent dose in Sv and rem
• Convert dose rates per second, minute, hour or day
• See one value in every other unit at once, rather than one pair at a time
• Access built-in radionuclide half-life data for 1,625 nuclides
• Use all calculation features without an internet connection

Gray and sievert are kept in separate tables. Converting between them requires a radiation weighting factor, which is a judgement about radiation type rather than a unit conversion, so DecayLab does not offer it.

DecayLab is useful for:
• Nuclear medicine technologists
• Medical physicists
• Radiation safety professionals
• Researchers and educators
• Students in nuclear medicine and related fields

Whether you're checking an activity value, preparing calculations for a workflow, or studying radioactive decay, DecayLab keeps the process clear and efficient.

Important: DecayLab is a calculation and educational tool. Results should be independently verified before being used in clinical, diagnostic, therapeutic, or safety-critical decisions.
