Description:

A small (14 cm long) cardboard box with shipping labels on two sides containing loose foam packing pieces and two small cylindrical aluminum containers.

The containers are open on one end with a narrow brim on the open end.

Primary Materials: Cardboard, Aluminum.

Markings:

Two labels (one address label, one Purolator courier label) indicate a shipment from the McMaster Nuclear Reactor in Hamilton, Ontario to the Department of Physics at the University of Toronto. The shipment is labelled “Attn P. Smith”.

Dimensions (cm):

Box: Heigth = 9.5, Width = 9.5, Length =13.

Function:

These aluminum containers held samples for shipment to and from the McMaster Nuclear Reactor and Derek York’s laboratory.

A cylindrical sheet of cadmium would have been added to the containers to surround the samples. The samples were irradiated in these containers to convert potassium 39 to argon 39.

Condition:

The surfaces of the aluminum cylinders are slightly worn. The box has been torn open along two sides of the top surface.

This artifact was among a number of artefacts collected on Friday, July 24th 2015 from the Potassium-Argon dating laboratory that was founded by Professor Derek York (1936-2007).

The laboratory was removed shortly after these items were gathered.
