Help needed on Calcium-41 and Nickel-59

[Simon "M." Jerome <smj1@npl.co.uk>]

Good afternoon.

We are doing some work on long lived electron capture radionuclides at 
NPL and I am finding it difficult to procure Calcium-41 and Nickel-59.

Does anyone out there know of a supplier of these radionuclides? They 
do not have to be standardised.

Thanks,
