1. Handheld survey meters

Detecting the surface contamination of the environment and on people
Low Range: at least 10 per hour of work up to
Designed to work long hours per category for the 1000 R"

Advantages:

• The meter-high radiation or nuclear facilities used for regulatory compliance.
• Professionals are very familiar with its use.

Limitations:

• Training more units are needed, and it may be displayed the ability to understand the use of checks."

2. Personal dosimeter

Small radiation monitor that is worn by a person

Passive equally divided doses cumulative assessment

Normal deposit amount after processing outside the workplace

A film TLD, OSL to contain radiation dosimeter directly to a normal person as ion storage detector" 

Advantages:

• It achieves a very good volume situation where warranted,
• OSL dosimeter Some are readily portable with a direct device toward hot zones and the next mission can read the first field assignment.

Limitations:

• Only record accumulated risk. As to avoid the lack of real-time display or alarm, it can help anxiety supplements of potential answers.

3. Pocket ionization chamber

Small, powerful, simple device worn by a person

Look for reading volume to look at the deflection of the needle through the device,

Usually the size of a large pen

Options for monitoring the various risk areas

Other names: Quartz fiber dosimeters own character pocket dosimeter, self-reading pocket dosimeter

"

Advantages:

• Can be read in real time, the user can avoid the worry supplements
• Minimal Maintenance
• Can be operated without batteries

Limitations:

• Do not alarm
• Must be charged before use
• The risk of such equipment to record readings are recorded at the end of a working period does not make any additions
• To read the user to wear respiratory PPE, especially when it can be difficult
• False readings that can provide mechanical confused available
• After a certain device must limit the dose selected for the wearer to protect the safety risks"

4. Electronic personal dosimeter

Long-haul, active dosimeters, professional radiation workers, regulatory compliance, industry and are usually worn in dangerous situations designed to measure the exposure held by the equivalence of individual doses for medical facilities

Displays dose and dose rate

Some careful if the default has been increased

Semiconductor detectors, such as the commonly used metal-oxide-semiconductor field-effect transistor"

Advantages:

• Proposals to immediately and alarm functions help to control risk
• When the dose rate is shown can act as per a survey

Limitations:

• Some devices are not suitable for tough emergency situation
• The lack of a larger display or loud enough to sound the alarm or was strong enough to move sideways
• Because they are used in amounts of more workers need to be able to make a more useful position of the user who changed the dimension of the emergency alarm button and additions to its regulator to confirm the ANSI standard.
• Standard measures 100 rem per hour per 100 SV REM (1 hour) hour (SV-1) threshold dose is required, but some devices will be more than that."
