Patent No. 9,457,382
We provide 100% Survey, with 0 volume averaging.
ISO Pacific offers the most advanced, robust, and highly efficient soil-sorting technology available. ISO’s patented S3 design and operational characteristics offer our customers the following benefits, none of which are found in total in any other system or company:
- Maximum mechanical reliability
- Unparalleled quality control features
- Unmatched field detection sensitivity
- Rapid calibration time
- Customer-Friendly data reporting
- Mobilization/demobilization costs half of current industry
- Ability to sort a variety of soils and materials
100% coverage means that the entire volume of the soil has been covered by the field of view of the scanning instrument and provides a high level of confidence that all areas of elevated activity will be identified. Scanning with 100% coverage with the S3 is much less expensive than finding areas of elevated activity later in the survey process.
- Soil types, include but are not limited to; wet clay, gravel, sand, ash rubble, construction debris, etc.
- Other material, included but not limited to; plant materials, metals, brick, foodstuffs, NORM scales, and more.
The benefits of nearly three decades of soil sorting experience and lessons learned have been built into our machine. The S3 is designed to handle a wide variety of soil types and their problem characteristics, including high moisture content, high plasticity, poor gradation, shear stresses and physical interference from organic matter and tramp debris, and many other phemonema associated with soil sorting.
Soil Sorting System (S3) Technology
The ISO Pacific S3 utilizes a 72″ wide sorter belt, which can accommodate a layer up to six inches in depth. The material is conveyed below the detector array in a thin layer whose depth and density is matched to the photon emission and attenuation characteristics of the contaminant of concern. There are no ‘guess-timates’ of attenuated subgrade activity that cannot be seen as with in-situ walkover scanning surveys. Production volumes can range from 80 to 200 cubic yards per hour.
A hallmark of ISO Pacific’s platform creation strategy is customization. State-of-the-art high-performance detectors are specifically chosen and placed in array formats tailor made to our client’s needs per project. Previous arrays have included options such as: specially-shaped tungsten wells for each detector; added “shadow” shield flat plates which helps to attenuate any photon emissions reaching detectors from the ground below the S3; methods to ensure the array is temperature controlled and monitored for humidity. ISO understands developing arrays with the project conditions in mind ensure client savings and no contaminant is missed.
Calibration is performed on-site, upon arrival, using the counter manufacturer’s automated calibration software. There are no delays associated with waiting for detectors and electronics to be calibrated off-site.
All MARSSIM prescribed quality assurance and quality control directives for the detection system are performed automatically via software algorithms. Human errors and bias have been removed from the equation.
Significant health and safety concerns can arise during any radiological survey – including the potential industrial hazards commonly found at any construction site. Using the S3 can help to minimize, avoid and even eliminate these potential safety hazards.
The S3 was designed to mitigate dust concerns from its inception. Nearly every portion of the plant is sealed or enclosed to provide positive dust control during operations.
Multiple software historians constantly record information and allow for simple and accurate preparation of shipping manifests and daily reports.
