Walton McCarthy is the president and principle engineer of Radius Engineering Inc. He is a mechanical engineer with a B.S. from Montana State University. He is a member of the American Society of Mechanical Engineers, The American Society of Testing and Materials, the Composite Fabricators Association, and serves on a technical Advisory Board for The American Civil Defense Association (TACDA).

Mr. McCarthy's research started in 1978 when he was privately funded for educational research which formed the basis of his first book, THE NUCLEAR SHELTERIST. He thereafter wrote PRINCIPLES OF PROTECTION, The US Handbook of NBC Weapon Fundamentals and Shelter Engineering Design Standards, known in the industry as POP. This book, now in its fifth edition for 2002, has become the engineering bible for shelter engineering in the US.

Mr. McCarthy has designed and built over 550 shelters using steel, concrete, wood, and fiberglass. Some of his contributions to the engineering and civil defense field include developing a new rating system for underground shelters to determine radiation doses inside a shelter known as the Total Rems in Shelter system or TRS; developing the Overpressure Choking Theory to negate the use of blast valves; developing fiberglass structures composed of multiple compound curves designed to resist multiple external pressures; and developing various underground shelter emergency escape methods.

Radius Engineering Inc. (bomb-shelter.net) has become the national leader in underground shelter technology.

Private Pilot

Walton is a private pilot which enables him to travel on his or the customer's schedule. When commercial airlines suffer from strikes, mechanical problems, scheduling problems, etc. Walton will find a way to make his appointment with his customer or outside contractors.

Ham Radio Operator KA5ENG

Walton has used his Ham radio experience to properly equip shelters and train shelterists to use a HAM radio enabling communication with other people without being dependent on the conventional telephone system which has proven to be undependable during disasters such as Hurricane Hugo, 911, Hurricane Katrina and Rita. Using the shelter radio package, shelterists can call for help, get medical advice, and report tactical information to First Responders, Red Cross, FEMA, Search and Rescue, contractors, etc. In the event that communication efforts fail, Walton holds a First Degree Black Belt in Taekwondo with both American and Korean certifications.

Commercial Driver License Class A

Sometimes drivers get sick on the road which affects when and how the customer will receive his/her shelter. The back-up driver that can always be counted on is Walton. He has significant experience in commercial driving of wide loads and has even designed the special trailer that hauls the company products. Radius makes an outstanding effort to see that the product is designed, produced and delivered properly to the customer. If Walton McCarthy is not able to solve your problem, you have really got a problem.
