During this pandemic, ARSAC has issued additional guidance. Due to the rapidly changing situation this should be considered alongside all current government guidelines:

Wherever possible, the patient’s best interest should be considered and individual patient circumstances should be assessed on a case by case basis prior to administration. This may result in some patient administrations continuing and some non-urgent or routine exams being cancelled or rescheduled.
The BNMS has additional resources here.
The Royal College of Radiologists has published guidance on non-urgent imaging here. Routine hospital attendances for patients should be stopped to reduce COVID-19 transmission. Imaging Departments should plan to minimise non-urgent imaging as they will have fewer staff available and more demand for in-patient services.
In a March 30 memo Nuclear Medicine Europe (NMEu) reported that NTP has informed them that the cessation of flights in and out of South Africa interrupted a bulk shipment of Mo-99 last week. Other options, such as charter flights, are being explored. However, other reactors have been able to maintain operation and production while protecting staff with additional measures.
ASNC held a webinar on preparedness for COVID-19. The slides are available here.
ASNC has a COVID-19 Resource Center for industry statements on status and operations during the pandemic. And, has published this guidance.
The BCS is collating a COVID-19 Clinicians Resource Hub outlining what is currently known & the latest advice for clinicians.

Stay safe everyone.
