Services

What you can hire Tenth Value for

Radiation protection design review

Use it when: your facility design needs a field-experienced check on shielding, radiation zoning and access control.

You get: a written list of issues and recommendations.

High-dose work review

Use it when: an upcoming job carries high dose or contamination risk, and you want its plan, sequence and shielding reviewed first.

You get: specific changes to lower dose and contamination risk.

Dose and contamination tracking

Use it when: your team finds overruns and contamination patterns too late, or tracks them across scattered spreadsheets.

You get: a simple dashboard adapted to your data. See an example

Past results

Problems solved in the field

Examples from the founder's work at operating nuclear stations.

Waste costs from unnecessary filter changes

Problem
Excess filter disposals and delays on an earlier unit.
Work
Modelled dose rates at remote detectors to support longer filter use, while keeping the direct-handling limit.
Result
Tens of thousands of dollars in disposal costs saved.

A stuck component above 1 rem/h

Problem
A high-dose component stuck at an angle in a waste container.
Work
Wrote the restrictions, worker-positioning boundaries and high-hazard plan, and requested a mock-up.
Result
The component was recovered successfully.

Reactor-face work that ran long

Problem
Seized hardware kept workers in gamma fields far longer than planned.
Work
Recalculated the dose impact and made the case for adding temporary shielding mid-job.
Result
About 2 person-rem saved by estimate, less than first hoped.

Repeat foot contamination

Problem
Oil soaking through standard booties during demobilization work.
Work
Added a full-coverage inner bootie and wrote a decontamination job aid.
Result
No further foot contamination events during that work.
