Key Points

Key Takeaways

  • 1

    Citizen Science

  • 2

    Scintillation Detector: Formal Geiger counter just beeped 'Gaga'. Latest scintillation detector analyzes energy of radiation (spectrum) and can identify 'Is it Cesium or Potassium'

  • 3

    Radiacode 103: Smartphone size revolution. Links with smartphone via Bluetooth, maps radiation dose in real time on Google Maps. Can make 'Radiation Map' by yourself

  • 4

    GQ GMC-600 Plus: High sensitivity model equipped with pancake tube, detecting even weak alpha rays. Suitable for measurement of food and ore

  • 5

    Background Radiation: When riding airplane, taking X-ray, or luminous paint of old watch. Everyday life is overflowing with radiation. Knowing that is entrance to science, not fear

Introduction: Obtaining Sixth Sense

We fear what we cannot see. However, if measurable, it becomes “Data”.

Modern Geiger counter is not just warning buzzer. It is environmental sensor and physics laboratory. Just by keeping in pocket, keep monitoring invisible energy of surroundings. That is acquisition of cyborg-like “Sixth Sense”.

1. The Pocket Spectrometer: Radiacode 103

Game changer developed by Cyprus company. Realized “Isotope Identification” which was only possible with conventional professional machine (millions of yen) with tens of thousands of yen.

Radiacode 103

Scintillation detector using crystal (CsI:Tl). Reaction speed is explosive. Road after rain, granite bench, inside aircraft. Enjoy change of numerical value in every place.

Radiation Mapping

Let’s go for a walk with smartphone app. Trajectory walked is color coded according to radiation dose (Green -> Yellow -> Red). Act of making own hazard map stimulates collection habit like Pokemon GO.

2. The Alpha Hunter: GQ GMC-600 Plus

Made by American GQ Electronics. Characterized by being equipped with large “Pancake Tube (LND 7317)“.

GQ GMC-600 Plus

Can ensure measuring alpha, beta, gamma rays separately. Pancake tube with large area is advantageous for measurement of food, water, soil contamination.

3. Comparison: Analysis or Measurement

項目 Radiacode 103 GQ GMC-600 Plus
Method Scintillation (Crystal) Geiger Muller Tube (Gas)
Nuclide ID Possible (Spectrum Analysis) Impossible (Count Only)
Alpha Ray Impossible High Sensitivity
Portability Micro (35g) Large (Smartphone size)

4. Why Measure?

“Ignorance is bliss”? No, knowledge is armor.

  • When buying suspicious souvenir in overseas travel (Uranium glass or Radium product).
  • When moving to new house (Natural radiation of building materials).
  • Exposure management as flight attendant.

By quantifying risk, we become able to make calm judgment (Risk Assessment).

Conclusion: Arm with Science

Pandemic and geopolitical risk. World does not know what happens. At that time, obtain primary information with device at hand instead of waiting for announcement of public institution.

That is correct attitude as Survivalist.
