EcoRIL²⁵ is an acronym for "Economical, Eco-friendly Radiation Indicator Labels for 25 kGy radiation absorbed dose indicators for medical sterilization application with advantages like, indigenous, low cost, environment friendly import substitute. The developed VOC free radiation indicator labels are intended to use in radiation sterilization of medical products, where the targeted dose is 25 kGy. As a part of ISO compliance, these radiation indicators are mandatorily to be pasted onto the consignment boxes, being subjected to sterilization process, for assuring various aspects of the irradiated medical products with added advantages.

1. Appearance of Deep Red color develops only at absorbed doses > 15kGy. Therefore, lower chances of ambiguity
2. Temperature independent color transition
3. Color transition independent of Dose Rate
4. Non-Toxic polymer based
5. Green route of preparation
6. No high skilled man power requirement
7. Minimum infrastructure requirement

1. To determine visually whether or not a product has been irradiated, rather than to measure different dose levels.
2. To segregate the sterilised product from un-irradiated unsterilized medical products at radiation processing plant.
3. In routine monitoring, load monitoring, and qualification of the radiation sterilization procedure and auditing of the records at the irradiation facility.

Sterilization of medical devices and surgical instruments/implants is of critical importance in the field of healthcare, because any unsterilized material that may come in contact with tissue or the mucus membrane of the patient during treatment, the various processes is associated with increased risk of introduction of pathogens into the patient's body. Therefore, adequate decontamination/sterilization techniques for medical and surgical devices are needed in all the health care procedures. Sterilization is decontamination process in which complete elimination or destruction (with SAL value ~10^-6) of all forms of microorganism, carried out by different physical and chemical methods. There are two most common methods of sterilisation of single use medical products adopted worldwide: ETO and radiation-based sterilization. There are two most common methods of sterilisation of single use medical products are: (i) Ethylene Oxide (ETO) treatment and (ii) radiation based (gamma, E-beam). In the Indian scenario, gamma radiation sterilization accounts for ~2 million cubic feet, i.e., 11 percent of the total volume of products sterilized.

1. Both base matrix and solvent are non-toxic in nature and therefore environment-friendly. This is in contrast to currently imported products whose fabrication process involves use of a number of toxic organic solvents.
2. It is capable of withstanding temperature up to 120°C i.e. EcoRIL²⁵ has high thermal stability and has negligible probability of undergoing color transition even when subjected to high temperatures.
3. The color transition demonstrated by EcoRIL²⁵ is independent of dose rate and therefore has wider acceptability irrespective of plant radiation parameters.
4. EcoRIL²⁵ is cost effective with current manufacturing price estimated at < Rs. 0.20 per label
5. It is an indigenous formulation developed under the "Make in India" initiative with the objective of replacing expensive import products.

1. To determine visually whether or not a product has been irradiated, rather than to measure different dose levels.
2. To segregate the sterilised product from unirradiated unsterilized medical products at radiation processing plant.
3. In routine monitoring, load monitoring, and qualification of the radiation sterilization procedure and auditing of the records at the irradiation facility.

1. Appearance of Deep Red color develop only at absorbed doses > 15kGy. Therefore, lower chances of ambiguity.
2. Temperature independent color transition.
3. Color transition independent of Dose Rate.

1. Dust free room with proper leveled table for film to ensure uniform thickness of radiation indicator labels.
2. Avoid direct sunlight or day light exposure.
3. Best used within 2 years of date of manufacturing.
4. Avoid exposure to moisture.
5. Store in leak-proof sealed opaque packaging.

1. Glass tray with flat Surface
2. Leveler (To maintain uniform thickness of PVA film)
3. Mechanical stirrer
4. Glass beakers
5. Volumetric flask
6. Measuring cylinders
7. Micro-pipette

Space

1. No requirement of large working space.
2. Dust free room.

Manpower

1. No specialist man power is required. Semi-skilled and/or skilled man power is sufficient which can be trained.

Test Equipment

1. Q&C of different indicator lots can be exercised with nearby radiation processing plant.
