Can I use a radiation detector check my home for radiation?
Yes. A radiation detector can: Measure background radiation levels Detect unusual increases Identify contaminated objects However: It cannot detect radon gas directly (special radon detectors are required)
Can Radiation Alert® Instruments detect RF Non-ionizing Radiation?
No
Can Radiation Alert® Instruments detect Microwaves?
No
Can Radiation Alert® Instruments detect Neutrons?
No
How does a Geiger‑Mueller (GM) Detector Work
1. Radiation enters the GM tube Radiation (alpha, beta, gamma, or X‑ray) enters a sealed tube filled with gas (usually argon or neon). The tube has: A central wire (anode) A cylindrical outer wall (cathode) High voltage applied between them 2. Radiation ionizes the gas When radiation passes through the tube: It knocks electrons off […]
Why choose Radiation Alert® detectors?
Designed and manufactured in the USA Trusted by professionals worldwide Wide range of detectors for every application Optional NIST‑traceable calibration Free software for data logging and analysis
Can a radiation detector identify radioactive materials?
Basic detectors → detect radiation only Advanced systems (MCA/spectroscopy) → identify isotopes
What level of radiation is dangerous?
Risk depends on dose over time, not a single reading. General guidance: Normal: background range Elevated: above background Concerning: sustained elevated readings Dangerous: high dose rate over time
Which radiation detector should I choose?
It depends on your application: Basic monitoring → GM detector High sensitivity → scintillation detector Personal safety → dosimeter Fixed installations → area monitor Isotope identification → spectroscopy (MCA)
What do µSv/hr, mR/hr, and CPM mean?
µSv/hr / mR/hr → radiation dose rate (exposure level) CPM / CPS → number of detected radiation events CPM = raw activity µSv/hr = biological impact
