Nuclear
Nuclear Radiation Shielding Calculator
Calculates the required shielding thickness to reduce gamma radiation from a radioactive source to a safe dose rate at a given working distance. Use it when designing barriers around radiation sources in medical, industrial, or nuclear facilities.

Nuclear
Nuclear Criticality Safety Calculator
Estimates the criticality safety margin for fissile material configurations by computing an effective neutron multiplication proxy based on concentration, geometry, moderator ratio, reflector thickness, and temperature. Used by nuclear safety engineers to assess subcriticality margins.
