My working career started as an engineer on board of oil tankers.

Further on I switched as an operator in the chemical industry and through courses and further education I became shift supervisor and a later on assistant Plant Manager.

Working in this industry I’ve got in touch for the first time with Radioactivity (NORM). My interest was aroused and 20 years ago I achieved level 5 of Radiation Protection.
That interest became the decision to become a Radiation Expert level 3.

Working as a Radiation Expert at Radiatco fits me as a glove, and being a senior with a lot of experience in the industry I am sure that customer orders will be filled in correct and adequate.

Supervising employee, radiation protection (former 5b)

The following (Dutch) profile text will be translated soon…

Tijdens mijn werkzaamheden als brand/veiligheidswacht in de kerncentrale Borsele werd ik geconfronteerd met radioactiviteit en de daarbij behorende straling en de stralingshygiëne. Er is toen nauw samengewerkt met medewerkers van Radiatco en zo is eigenlijk mijn loopbaan in de stralingshygiëne begonnen. Door de directeur van Radiatco is mij gevraagd een opleiding in die richting te gaan volgen en dat heb ik eind 2017 met het behalen van het diploma Ioniserende straling niveau CI-5B afgesloten. Vanaf die tijd ben ik werkzaam als medewerkster van Radiatco en heb al op diverse locaties werkzaamheden verricht in de industriële sector en in de offshore sector. Door mijn praktische kijk en technische achtergrond vind ik al snel mijn weg op industriële locaties. Mede door mijn ervaring als brand/veiligheidswacht is het inpassen van stralingshygiënische maatregelen mij op het lijf geschreven.

Name: Joost van Loo

In training for supervising empolyee, radiation protection (former 5b).

The following profile text will be translated soon.

Sinds maart 2018 ben mijn carrière in de stralingswereld bij RadiatCo begonnen. De vier voorgaande jaren ben ik als promovendus werkzaam geweest op de WUR in Wageningen. Het onderzoek wat ik daar heb uitgevoerd was gericht op de darmflora van vissen en was daardoor veelal microbiologisch van aard. Tijdens dit werk heb ik veel onderzoeks- en laboratorium ervaring opgedaan. De opleidingen die ik heb doorlopen zijn HBO Milieukunde aan de HAS in ’s-Hertogenbosch. De studie milieukunde is een zeer brede opleiding die is gericht op het oplossen en begeleiden van milieukundige vraagstukken in de breedste zin van het woord. Na de studie Milieukunde ben ik naar de WUR in Wageningen gegaan om me te specialiseren doormiddel van de Master-opleiding “Aquaculture and Marine Resource Management”.
Begin 2019 hoop ik mijn opleiding tot stralingsdeskundige niveau 3 te behalen en tot die tijd een hoop ervaring op te doen binnen allerlei projecten.
