The journey of ISI, from founding to growth, acquisition and rebranding.

Legacy companies
Our legacy company ISI and their integration into the Life Couriers group.
Founded in 1987 in Zaventem, Belgium, ISI established itself as a specialist in the international distribution of short-lifetime products for the radiopharmaceutical market.
As a licensed carrier and storage facility certified by the Belgian nuclear authority (FANC) for the transport of radioactive and industrial isotopes across Europe, ISI developed deep operational experience in one of the most demanding logistics niches.
Today, the same team, drivers and facilities continue under the Life Couriers name. Strengthened by a global radiopharma network and customer base, they continue their mission to serve patients across the world with vital radiopharma deliveries.
The journey of ISI, from founding to growth, acquisition and rebranding.


At the heart of ISI’s operations was a strong commitment to safety, regulatory compliance and reliability.
ISI is certified and licensed to store and transport radiopharmaceuticals and radioactive isotopes – a testament to its high‐standard compliance culture.
The company’s operations focus on short‐lifetime products: meaning high time-sensitivity, stringent cold-chain and rapid delivery demands.
ISI’s culture and deep understanding of the mission: behind every shipment is a vital health or life science application for a patient.

ISI (Isotopes Services International) built a robust distribution network for radiopharmaceuticals and industrial isotopes throughout Europe, leveraging its Belgian hub. Now this legacy continues on as part of the global Life Couriers Radiopharma network.
The acquisition of ISI by Life Couriers brings together a proven Belgian specialist with a global logistics network:
Life Couriers offers global Radiopharma logistics; ISI brings deep regional expertise in Belgium and Europe for isotope transport.
ISI’s proven track record in short‐lifetime, highly regulated isotopes complements Life Couriers’ broader portfolio in cell therapy, biologics, biosciences and pharma freight.
Clients of ISI will benefit from the global systems, investments and brand of Life Couriers, while preserving the operational reliability they’re used to.
Both companies emphasise that logistics is not just about freight – it’s about enabling health, care and research.
As ISI becomes fully integrated under the Life Couriers brand, you can expect:
Consistent quality and compliance standards, elevated by global best practices.
Efficient, transparent services, improved tracking and digital tools.
Broader service offer and scalability, without compromising the agility and local responsiveness you value.
The same teams and same commitment, now backed by a global network.
Since 1987, ISI provided radiopharma and nuclear medicine pioneers with the highest quality transport services inside Belgium and across Europe.
Those values now live on in Life Couriers, a global group rooted in service excellence and supporting patients in need. We strive to grow our position as the global leaders in radiopharma logistics, continuing on the legacy of ISI and the other legacy companies that paved the way.
Life Couriers is the global leader in saving lives and trusted advocate for the good of patients, with the broadest service portfolio on the market.
