    It is intended for personal safety and educational purposes.

    Like the popular Radalert® 100X, the RAD 100™ features a 3-second update on its digital liquid crystal display (LCD). The LCD shows the current radiation level in your choice of microsieverts per hour (SI units) from .000 to 1,100, either counts per minute (CPM) from 0 to 350,000 or counts per second (CPS) from 0 to 3,500. When mR/hr units are selected, the LCD shows readings in milliroentgens per hour from .000 to 110. This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours. A red LED blinks and a beeper chirps with each count (the chirp can be muted).

  • CT007-Radiation Response Kit (02)

    CT007-Radiation Response Kit (02) $1,400.00

    The Pancakes Kit includes two CT007-P pancake detectors and a telescoping handle in a rugged protective case. This kit is ideal for First Responder teams. For hot zone / cold zone delineation, one CT007-P is used in dose rate mode and the other is used in contamination mode. During decontamination, both detectors are used in contamination mode. The redundancy achieved by using two identical instruments for different tasks means that all tasks can still be performed, even if one of the detectors is damaged. Also, one CT007-P can be used to confirm the reading of the other one. The kit can be supplied with only one CT007-P (Kit-01) and the CT007-P is also available without accessories.

Alternatively, the CT007P may be wirelessly linked to your smartphone with the readings displayed on the phone’s screen. This allows you to take readings in locations that are not in line of sight. A telescoping handle is provided for access at a distance. The phone can be clipped to the handle, enabling one-handed operation. The Smartphone provides a large display with access to a feature-rich menu. The cordless connection to your Smartphone has a range of approximately 40 m and the telescoping handle can be extended with an ordinary painter pole. The GammaGuard app, running on your smartphone allows you to log data to a file on the phone or upload data to RadResonder, a web based database. You can use earphones, connected to the phone, to hear beeps or alarms in noisy environments.
