Radiansa: radiation measurement and shielding


radiacion de antenas

Hand-held radiation survey meters
and general-purpose Geiger counters

Portable Geiger-type radiation monitors used for a wide range of radiation measurement applications; used to measure radiation levels, quantify surface contamination, detect X-ray leakage, warn of elevated radiation levels, conduct contamination surveys, etc.


PM1405 Radiation survey meter

PM1405 radiation detector

Used for a wide range of radiation monitoring applications, including measurement of ambient gamma radiation, X-ray leak detection, search and measurement of radioactive contamination, and specific measurement of surface contamination by beta emitters.

A movable screen covers the entrance window, to enable discrimination between gamma, and beta/alpha radiation; with the screen inplace, the monitor acts as a compensated Geiger monitor for gamma radiation dose measurement, while uncovering the screen allows the monitor to measure lower energy X-ray and gamma radiation, and alpha/beta radiation.

Dose rate mode, cps mode, and surface contamination mode reading beta radiation flux levels.

Activates an alarm if radiation levels exceed a pre-set threshold.

Supplied with software and USB and cable to enable real-time visualization of radiation level on a PC, change instrument configuration, and retrieve data stored in the instrument's memory.

RANGER Radiation survey meter

Ranger Hand-held radiation detector

Easy-to-use professional survey meter, used for a wide range of radiation detection applications, including search and detection of radioactive materials, X-ray leak detection, and radioactive contamination surveys.

Large-area 45 mm diameter pancake-geometry Geiger tube with mica window, sensitive to alpha, beta, gamma radiation and X-rays (down de 10 keV).

Protective rubber body ideal for industrial envirnoments.

The instrument activates an alarm if radiation levels exceed a pre-set threshold.

The large digital display can be switched between count rate and dose rate modes.

With a USB connection, the instrument is supplied with a software package (Observer software) to enable real-time visualization of count rate data on a PC, together with data storage and statistical manipulation.

Radalert100X Radiation survey meter

Radalert100X Hand-held radiation detector

A popular, reliable and easy-to-use general purpose radiation detector incorporating a cylindrical-geometry Geiger tube with mica window, sensitive to alpha, beta, gamma and X-radiation.

The instrument activates an alarm when radiation levels exceed a pre-set threshold.

The large digital display can be switched between count rate and dose rate modes.

The LCD shows readings in microsieverts per hour from .01 to 1100 or counts per second (cps) from 0 to 3,500 (the display can be switched to read milliroentgens per hour from .001 to 110 or counts per minute (cpm) from 0 to 350,000.)

A submini jack provides audio output to an external earpiece or amplifier. As an optional extra, the RadAlert100 can be supplied with a software package and communications cable to enable real-time visualization of count rate data on a PC, together with data storage and statistical manipulation. Dose rate reading updated every 3 seconds.

Features timer function to accumulate counts within a set time period.

RAD100 Radiation survey meter

RAD100 Hand-held radiation detector

A general purpose radiation detector sensitive to alpha, beta, gamma and X-radiation based on the Radalert100X but without the alarm function.

The large digital display can be switched between count rate and dose rate modes.

The LCD shows readings in microsieverts per hour from .01 to 1100 or counts per second (cps) from 0 to 3,500 (the display can be switched to read milliroentgens per hour from .001 to 110 or counts per minute (cpm) from 0 to 350,000.)

A submini jack provides audio output to an external earpiece or amplifier. As an optional extra, the RadAlert100 can be supplied with a software package and communications cable to enable real-time visualization of count rate data on a PC, together with data storage and statistical manipulation. Dose rate reading updated every 3 seconds.
