The Cabrera Services iPhone App contains a variety of Calculators and reference material which are of value to professionals involved in radiological engineering and services.

Reference Section

• Specific Activity Calculator
  Provides radioactivity (microcuries) per unit mass and inverse for selected radioisotopes.
• Uranium, Depleted Uranium, and Thorium Decay Chains
  Provides radioactivity percent levels of radioisotopes present in chemically separated metal and compounds as a function of time.
• Actinium, Thorium, and Uranium Decay Series
  Provides naturally occurring radioisotopes present in equilibrium decay chains. Accompanying data includes the radioisotope, half-life, principle decay modes, and up to 3 most significant alpha, beta, gamma ray and X-ray emissions with energy (keV) and intensity (%).

Calculators Section

• Airborne Minimum Detectable Concentration Calculator
  Calculates the alpha and beta minimum detectable concentration based on 8 input factors for air samplers.
• Radioactivity Conversions
  Industry standard conversions between units of curies, disintegrations per unit time, and Becquerels.
• Dose Equivalents
  Industry standard conversions between rem, Siverts, and DAC-hr.
• Derived Air Concentration Percent
  Provides estimated percent of 10CFR20 Derived Air Concentration for selected radionuclides based on soil concentration and measured airborne dust concentration.
• Permissible Exposure Limit for Airborne Metals and chemicals
  Provides estimated Permissible Exposure Limit for various metals and chemicals based on soil concentration and measured airborne dust concentration.
