Radiation hazards
Exposure rate
Environment; Radiation hazards
The amount of ionisation in air caused by x-ray or gamma ray radiation per unit time; unit of measurement is the Roentgen per unit time (R/hr)
Dosimeter
Environment; Radiation hazards
A portable instrument for measuring the total accumulated exposure to ionising radiation.
X-rays
Environment; Radiation hazards
Penetrating electromagnetic radiation (photon) having a wavelength that is much shorter than that of visible light. They can be produced by excitation of the electrons around certain nuclei ...
Wipe sample
Environment; Radiation hazards
Wiping of 100 square centimetres of a surface with a philtre paper or a cotton swab for the purpose of determining if removable contamination is present. The wipe is then analysed with a radiation ...
Survey metre
Environment; Radiation hazards
Any portable radiation detection instrument especially adapted for inspecting an area to establish the existence and amount of radioactive material or contamination present.
Thermoluminescent dosimeter (TLD)
Environment; Radiation hazards
A crystalline material which emits light when heated after radiation exposure; used in dosimetry.
Shielding
Environment; Radiation hazards
Any material or obstruction that absorbs radiation and thus tends to protect personnel or materials from the effects of ionising radiation.
