RADIATION SENSITIVITIES OF DIACETYLENES

Diacetylenes  (R-C≡C-C≡C-R) instantly polymerize only in the solid state to colored polymers (polydiacetylenes) upon exposure to ionizing radiation and heat. Hence, they can be used for monitoring radiation and time-temperature.

Different diacetylenes with varying levels of sensitivity (0.02 Gy to 50 Gy) are selected to meet the specific requirements of different applications.

COLOR DEVELOPING RADIATION DOSIMETERS

  • Materials: Specialty diacetylenes.
  • Colors: Colorless to blue, purple or red.
  • Dose ranges:
    • ~20 mSv (0.02 Gy) to 10,000 mSv (10 Gy) for personal emergency radiation dosimeters e.g., RADTriageTM.
    • 10 Gy to 100 Gy for blood radiation indicators.
    • 0.02 kGy to 5 kGy for monitoring radiation of tubers, fruits, vegetables, grains, legumes and nut.
    • 1 kGy to 10 kGy for monitoring radiation of meets and fish.
    • 5 kGy to 20 kGy for monitoring radiation of spices.
    • 5 kGy to 50 kGy for monitoring sterilization of medical supplies.
  • Shelf-life: 2 to 5 years at room temperature.
  • Effect of UV/sunlight: Negligible. Little effect of 1 day of sunlight.
  • Effect of humidity: None to negligible.

COMPETITION

  • Affected by ambient conditions: Very sensitive to ambient conditions such as UV/sunlight and humidity.
  • Cold storage requirements: Products are based on diacetylenes having low melting point (~60oC) and hence require cold storage. The shelf life of months at room temperature.
  • Expensive raw materials: Multi-step, complex synthesis and purification and hence expensive.

JP LABS’ DOSIMETERS

  • Effect of ambient conditions: Essentially no effect of room ambient light, negligible effect of sunlight for one day and none to negligible effect of ambient humidity.
  • Shelf-life: Products are based on diacetylenes having high melting point (>100oC) and hence require no cold storage. The shelf-life is at least two years at room temperature.
  • Affordable raw materials: Single-step synthesis of high purity, high yield diacetylenes from the raw materials.
