Procedural Separation Question
What are the criteria used to seperate IFR traffic by radial? For instance, if I am on a departure clearance tracking a radial out from a facility, when can inbound traffic (on a different radial) be cleared through my level, if we at similar DME?

In the example you stated,
Using a VOR and associated DME/TACAN station. Both aircraft must have reported established on radials at least 20° apart.
One aircraft inbound and the other outbound from the VOR station, [track separation is established], provided that the outbound aircraft is at least 20 miles OR the inbound at least 30 miles from the station.
There are other criteria for two a/c inbound or two a/c outbound. These, and conditions attached to the separation standards can be found in CAP 493, Manual of Air Traffic Services (part 1), Section 1 Chapter 3.

You are quoting from UK separations. The enquirer is not from the UK and ICAO does not admit to such a separation, therefore it would be specified by the individual State.

2 Sheds is correct.
ICAO standards can be found in Doc 4444. Section 3 for Area Control and Section 4 for Approach Control.

Ahhh . The joys of ICAOstandardisation - not!!
And why do they (ICAO) exist again?
Lat sep tables are published Downunder in MATS. I think they were created by a guy in the mil who actually got a medal/ recommendation for it!!
No use in the UK as the airspace cant be policed / owned / monitered - far too small and too many unknown users therein!

Re various comments above about "standards" and "standardisation", these are not quite accurate. The separation minima (the UK confuses the issue by referring to "separation standards"!) are specified in PANS, not as Standards or Recommended Practices (SARPS) as such.
From ICAO...
"The Procedures for Air Navigation Services (PANS) do not have the same status as the Standards and Recommended Practices. While the latter are adopted by Council in pursuance of Article 37 of the Convention on International Civil Aviation, subject to the full procedure of Article 90, the PANS are approved by the Council and recommended to Contracting States for world-wide application.
Whilst the PANS may contain material which may eventually become Standards or Recommended Practices (SARPs) when it has reached the maturity and stability necessary for adoption as such, they may also comprise material prepared as an amplification of the basic principles in the corresponding SARPs, and designed particularly to assist the user in the application of those SARPs.
The implementation of procedures is the responsibility of Contracting States; they are applied in actual operations only after, and in so far as, States have enforced them. However, with a view to facilitating their processing towards implementation by States, they have been prepared in language which will permit direct use by air traffic services personnel and others associated with the provision of air traffic services to international air navigation."
