The Dosimeters Measure Radiation Exposure Over Time To Ensure That A Harmful Dose Is Not Received
Dosimeters |
Radiation with ions can be dangerous. At its best, radiation
exposure results in radiation sickness and/or burns; at its worst, it is lethal
or the source of terminal malignancies and other potentially fatal medical
disorders. Fortunately, radiation Dosimeters are available in a variety of shapes
and sizes, but they are all intended to monitor the concentrations of dangerous
ionising radiation as a precaution.
Since gradual, ongoing low-dose ionising radiation exposure
is as dangerous as acute, high doses in a single exposure, smaller models can
be worn by people working in radioactive environments to monitor their exposure
in real-time as well as to keep track of cumulative exposure overtime. They are a common instrument in the
fields of radiation dosimetry and radiation health physics, as well as in
radioactive businesses and occupations.
To monitor exposure to gamma radiation, x-radiation, and
high-energy beta radiation, these devices are constructed with
radiation-sensitive materials (such as P-32). Some Dosimeters can measure and record instantaneous, localised
radiation exposure in addition to whole body doses.
Radiation badges are the kinds that workers who are exposed
to ionising radiation wear; they can be fastened onto their protective
equipment.
Those whose jobs expose
them to maximum exposure levels are most likely to wear and utilise radiation
dosimeters:
·
The
annual occupational whole body dosage cap is 5,000 millirems.
·
The
maximum annual dose for the extremities (hands, fingers, etc.) is 50,000
millirems.
To keep worker radiation exposure well below the maximum
levels, dosimeters and radiation badges are crucial components of any company's
radiation safety programme and should be used consistently and meticulously in
accordance with manufacturer's guidelines. To keep workers safe, dosimeters
should be used in accordance with industry best practises, together with all
the required radiation shielding and protective gear.
