Homework Help Overview

The discussion revolves around calculating the delivery time for two nuclides, A and B, produced in a reactor and separation plant. Nuclide A has a half-life of 23 minutes and is a beta-only emitter, while nuclide B has a half-life of 23 days and emits both beta and gamma radiation. The original poster is attempting to understand the implications of the activity levels of these nuclides during the delivery process.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to apply a formula related to activity to determine the delivery time, expressing uncertainty about the relevance of the 11.5 minutes of purification. Some participants question the clarity of the problem statement and the implications of the activity remaining constant during delivery.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. There is a request for clarification from one participant regarding the original poster's statements, indicating that the problem may not be fully articulated. No consensus has been reached yet.

Contextual Notes

The original poster mentions a specific activity level of 1000 gamma rays per second for both the purified nuclide A and during delivery, raising questions about the timing and implications of this consistency. The mention of a courier company adds an informal aspect to the discussion but does not contribute to the scientific inquiry.

In a reactor and sepertation plant complex, nuclide A is produced in pure form, without any contamination by nuclide B.

A has a half life of 23minutes and B has a half life of 23days. A is a beta only emitter whereas B is a beta and gamma emitter. If A has been purified in a reatcor and 11.5minutes of purification it emmits 1000gamma rays per second and when delivered it also emits 1000gamma rays per seconf, how long did the delivery take?

Secondly if this was delivered to you by a courier company would you use them again?

I have used n(t) =No*lambday/(lambay-lambdax) * (e-lambdax*t - e-lambday8t)

So guessing this is something about activity, but can't quite get it. think the answer is 40.7days but not sure how to come to this************************************************************************

How does this affect the problem... the 11.5minutes.

A is a beta only emitter whereas B is a beta and gamma emitter. If A has been purified in a reatcor and 11.5minutes of purification it emmits 1000gamma rays per second and when delivered it also emits 1000gamma rays per seconf, how long did the delivery take?

Your statements are a little confusing. If the activity is 1000Bq, then delivered, and it's still 1000Bq, then statistically no time has passed for the delivery. Can you restate the problem in its entirety?
 
That is the problem in it's entirity...
 
Anyone have any ideas?
