whole body dosimeter

Text description

A front view of a single dosimeter that is rectangular in shape and royal blue in color that has an aperture at the top and bottom. A white label has Group: A12345 printed at the top centre, the users name Paul B SMITH, printed below and the dosimeter serial number 483031 is printed at the bottom with a 2D barcode to the left and another 2D barcode to the right. The wearing period start date 2016/01/01 and end date 2016/03/31 is printed in the top right corner and is highlighted by a yellow textbox. The Health Canada and Canadian flag logo appears in the bottom right corner of the white label and just below this is the acronym NDS-SND. The top left side of the label has a red rectangular textbox with InLight centered above a character. Appearing over the heart area of the character is a square black box, which represents the dosimeter wearing location.

Extremity dosimeters

Ring Dosimeter

extremity dosimeter

Text description

Two dosimeters that are ring-shaped. On the right is a small sized ring, orange in colour. On the left is a large sized ring, blue in color. Both rings have a dosimeter serial number, 2D barcode and wearing period start date Oct 01 20 centered on a white oval label.

Dosimeter overview

The ring dosimeter uses thermoluminescence (TLD) technology to monitor exposure to X-ray, beta and gamma radiation.

The ring dosimeter is made by enclosing a thermoluminescent chip underneath the ring cap, which is ultrasonically welded to the ring base. Each ring has an identification label pasted on top. All ring dosimeters are labelled with the:

Inlight Nova Extremity Dosimeter

The InLight Nova extremity dosimeter uses Optically Stimulated Luminescence (OSL) technology to monitor exposure to X-ray, beta and gamma radiation. The dosimeter is fastened to the wrist or ankle using a Velcro®strap. The wrist and ankle dosimeters are labelled with the:

extremity dosimeter strap

Text description

A single dosimeter that is rectangular in shape and royal blue in color. A white label has Group: A12345 printed at the top centre, the users name Paul B SMITH, printed below, and the dosimeter serial number 483034 is printed at the bottom with a 2D barcode to the left and another 2D barcode to the right. The top left side of the label has a red rectangular textbox with InLight centered above a character. Appearing over the right wrist of the character is a square black box, which represents the dosimeter wearing location. A textile black thin strap with a Velcro fastening mechanism is attached to the top and bottom of the dosimeter.

Client suitability

Ring, wrist and ankle dosimeters can be used by individuals whose extremities are at risk of radiation exposure, such as:

neutron dosimeters

Text description

Two neutron dosimeters that are side by side. The neutron dosimeter to the left has the front view and the neutron dosimeter to the right has the back view. The front view neutron dosimeter is flat and white in color. A barcode appears at the top of the dosimeter and below the barcode is the letter x with the numbers 02/01/04. The bottom left corner has the numbers 181724. The back view neutron dosimeter is also flat and white in color. A black rectangular box appears to the left of the dosimeter and a 3D barcode appears to the right of the dosimeter. Each neutron dosimeter is inside a clear vinyl pouch. The clear pouch is flat and has a metal and clear vinyl fastening clip attached to the top.

Neutron dosimeters

Dosimeter overview

Neutron dosimeters use solid state nuclear track detector technology (CR-39) to monitor exposure to neutron radiation. The dosimeter is packaged in a vinyl pouch specifically designed for neutron detection.

Clients who use the neutron dosimeter may also monitor a broad spectrum of ionizing radiation by using a Whole Body Dosimeter (InLight Nova).

Client suitability

Neutron dosimeters can be used by individuals who may be exposed to neutron radiation, such as:

Electronic personal dosimeters

Electronic personal dosimeters

Text description

Front view of a single electronic personal dosimeter (EPD). The EPD is rectangular shaped, off white in color and has a black lid on the top. On the front side, near the bottom is an orange/reddish circle and above this is a small orange light. There is a black circular knob on the left side of the dosimeter, near the top and a black oval button, on the front side, near the top. SIEMENS is written in black capital letters just below the black oval button.

Dosimeter overview

The Electronic Personal Dosimeter, or the EPD® as it is more commonly called, detects and monitors exposure to X-ray, beta and gamma radiation in real time.
Radiation that is detected by the EPD is processed to give a real time readout to the user via a liquid crystal display (LCD) for deep dose, skin dose and dose rates.

Client suitability

EPDs can be used by individuals who need real-time personal monitoring for dose management purposes such as:
