Reflection and Nuclear Radiation Concepts

Abimat

A term likely referring to a specific type of mirror or reflector.

Angle of Reflection

Angle at which light reflects off a surface.

Curved Reflections

Used in transmitters and receivers of waves.

Transmitter

Device placed at focal point for signal emission.

Angle of Incidence

Angle between incoming wave and normal line.

Total Internal Reflection

Light reflects completely within a medium beyond critical angle.

Critical Angle

Angle in glass causing refraction of 90 degrees in air.

Nuclear Radiation

Radiation emitted from unstable atomic nuclei.

Alpha Radiation (α)

Consists of 2 protons and 2 neutrons.

Beta Radiation (β)

Fast-moving electrons emitted from radioactive decay.

Gamma Radiation (γ)

High-energy electromagnetic radiation emitted during decay.

Activity (A)

Number of decays per second in a radioactive source.

Becquerels (Bq)

Unit of measure for radioactive decay activity.

Absorbed Dose (D)

Energy absorbed per unit mass from radiation.

Grays (Gy)

Unit of absorbed dose in radiation physics.

Equivalent Dose (H)

Dose adjusted for biological effect of radiation type.

Sieverts (Sv)

Unit for measuring equivalent dose of radiation.

Weighting Factor (Wp)

Factor accounting for radiation type's biological impact.

Background Radiation

Natural radiation present from cosmic and terrestrial sources.

Example Calculation

Method to determine absorbed dose using given values.

Absorbed Dose Calculation

D = E/m, where E is energy and m is mass.
