Radioactive Models Chelmsford [new] -

Local hobbyists and ex-Marconi engineers often commissioned custom radioactive source models for training. Over time, became a collector’s code for any pre-1970s British nuclear training aid that originated from the Essex tech corridor.

| Model Type | Description | Example Application in Chelmsford | |--------------------------------|-----------------------------------------------------------------------------|---------------------------------------------------| | | Solve differential equations for parent-daughter decay. | Medical tracer calibration (Broomfield Hospital) | | Transport models (Monte Carlo) | Simulate photon/neutron paths through matter. | ARU research; e2v radiation hardness testing. | | Compartmental bio-kinetic models | Track radioisotope movement in organs/blood. | Nuclear medicine dosimetry planning. | | Dose prediction models | Relate exposure to health effects (e.g., ICRP models). | Occupational radiation safety in labs. | | Physical phantom models | Human-shaped or slab phantoms with embedded radioactive sources. | Gamma camera calibration (hospital). |

: While initially a local hobby shop in Chelmsford, the brand evolved into Radio Active Manufacturing, specializing in the design and production of RC components and accessories for the global modeling community.

: The manufacturing arm of the business eventually moved from Chelmsford to a new facility in Droitwich, Worcestershire . | Medical tracer calibration (Broomfield Hospital) | |

Most were produced in runs of fewer than 100 units. Many were discarded when schools updated their curricula. Those that survive are exceptionally rare.
