research aims to obtain the most reliable ΔR results possible using known
age shells collected prior to the detonation of thermonuclear weapons.
These guidelines have been compiled in order to facilitate the search
for suitable shells.
1. Shellfish must have been collected live.
2. Collection date must be known, and date of collection must be before 1950.
3. The geographic location of shellfish when collected must be known.
Other useful information:
1. Name of museum and if possible name of collection/museum acquisition number for each shell.
2. Year of museum acquisition (may be different from year of collection).
3. Name of original collector.
4. Name of submitter (you!).
5. Family, Genus & Species name.
6. Dietery preferences (eg. carnivore, filter feeder etc)*.
7. Habitat (eg. open marine, estuarine, etc).
*Dietary information for a number of shellfish species can be found in the Shellfish Database.
