In this section of the\u00a0Bulletin<\/em>, we introduce a question or two similar to the questions on the CRPA(R) exam. In the next issue, we will provide the solution. The intention is to give people an idea of the types of questions we use on the CRPA(R) exam and perhaps convince more members to challenge the exam.<\/p>\n

The CRPA(R) designation is the highest level of competency recognized by CRPA at the Canadian level. To find out more, visit the CRPA website<\/a>.<\/p>\n

If you are interested in obtaining the CRPA(R) designation, we recommend you apply soon<\/a> to ensure you can write the exam in June 2020! The application deadline is April 9, 2020.<\/p>\n

If you already have your CRPA(R) designation, we invite you to\u00a0submit questions<\/a>\u00a0to earn points for your registration maintenance!<\/p>\n

Question from the last issue:<\/h1>\n

Let\u2019s take a look at the solution to the question from the last issue. We went back to some calculations.<\/p>\n

A gamma counter produces a measurement of 1,805 counts over a five-minute period. What are the count rate and the associated standard deviation?<\/p>\n

a. 361 \u00b1 115 cpm
\nb. 361 \u00b1 75 cpm
\nc. 361 \u00b1 9 cpm
\nd. 361 \u00b1 11 cpm<\/p>\n

This is another good question for all you calculation lovers out there! We took it up a notch this time with the inclusion of uncertainties and error. Like last time<\/a>, you shouldn\u2019t have any problems solving the problem with general knowledge of counting instruments and associated calculations. Things can get tricky with uncertainties, though\u2014but that\u2019s why you prepare for these exams!<\/p>\n

As I have mentioned many times in previous CRPA(R) Prep columns<\/a>, when it comes to instrumentation and counting, my favourite \u201cgo-to\u201d resource is Knoll\u2019s Radiation Detection and Measurement<\/em>.[1<\/a>] There\u2019s an entire section of the book dedicated to the propagation of errors in calculations. This book is part of the recommended reading list in the CRPA Radiation Safety Professional Registration Process Document<\/a> on the CRPA website.<\/p>\n

Getting back to our question, count rate is given by:<\/p>\n

\"\"<\/p>\n

We know the count rate in this example is 361 cpm. (We didn\u2019t even need to calculate this\u2014it\u2019s the only option provided!) The corresponding standard deviation for total counts is given as:<\/p>\n

\"\"<\/p>\n

So, the standard deviation for counts is given by the square root of 1,805.<\/p>\n

Now, here is the key piece of information. Typically, it is assumed that time is measured with very small uncertainty\u2014so small that we can, by convention, consider it constant.<\/p>\n

So, even without heeding the obviously sound advice of the Registration Subcommittee and using the recommended reading list, you can reach into the far recesses of your mind\u2014go back to your early lab courses\u2014and recall error propagation.<\/p>\n

Error propagation for division by a constant (in this case, time) involves finding the fractional error. In this example, that is given by:<\/p>\n

\"\"<\/p>\n

So, our final answer before rounding looks like 361 \u00b1 8.497 cpm. By some conventions, the uncertainty error is always rounded up. (You don\u2019t become MORE certain going to one signification figure.) In any case, the closest answer is c, 361 \u00b1 9 cpm.<\/p>\n

Some people might be inclined to calculate the rate first, then take the square root of that result (361 \u00b1 19 cpm). Others might want to quote only the uncertainty in the counts (361 \u00b1 42 cpm). In this particular example, you will know right away that you are not on the right track, as those answers are not offered for this question. Other questions might not be as generous and may have distractor answers that include common miscalculations. Be careful out there! Check your work!<\/p>\n

The question for next time:<\/h1>\n

You have a 555 MBq Ni-63 sealed source in permanent storage. How often must a leak test be conducted?<\/p>\n

a. Once a month
\nb. Every 12 months
\nc. Every 24 months
\nd. Only when the source is disposed of<\/p>\n

Dans cette section du Bulletin<\/em>, nous pr\u00e9sentons une ou deux questions similaires \u00e0 celles qui se trouvent dans un examen pour l\u2019agr\u00e9ment (A)ACRP, puis nous publions la solution dans le num\u00e9ro suivant. Le but est de donner aux gens une id\u00e9e du type de questions pr\u00e9sent\u00e9es dans un examen d\u2019agr\u00e9ment et de convaincre davantage de membres de passer l\u2019examen.<\/p>\n

La d\u00e9signation (A)ACRP est le niveau de comp\u00e9tence le plus \u00e9lev\u00e9 reconnu par l\u2019ACRP au niveau canadien. Pour en savoir plus, visitez le site Web de l\u2019ACRP<\/a>.<\/p>\n

Si vous souhaitez obtenir la d\u00e9signation (A)ACRP, nous vous recommandons de d\u00e9poser votre candidature bient\u00f4t<\/a> afin de vous assurer de pouvoir passer l\u2019examen en juin 2020! La date limite pour s\u2019y inscrire est le 9\u00a0avril 2020.<\/p>\n

Si vous avez re\u00e7u la d\u00e9signation (A)ACRP, nous vous invitons \u00e0 soumettre des questions<\/a> pour cette chronique afin d\u2019obtenir des points pour le maintien de votre agr\u00e9ment!<\/p>\n

Question du dernier num\u00e9ro :<\/h1>\n

\u00c9tudions la r\u00e9ponse \u00e0 la question du dernier num\u00e9ro. Nous \u00e9tions de retour aux calculs.<\/p>\n

Un compteur gamma mesure 1\u2009805 comptes sur une p\u00e9riode de 5 minutes. Quels sont le taux de comptage et l\u2019\u00e9cart-type associ\u00e9?<\/p>\n

a. 361 + 115 cpm
\nb. 361 + 75 cpm
\nc. 361 + 9 cpm
\nd. 361 + 11 cpm<\/p>\n

Encore une fois, il s\u2019agit d\u2019une bonne question pour les amateurs de calculs! Nous avons \u00e9lev\u00e9 le niveau d\u2019un cran cette fois-ci en ajoutant des incertitudes et des erreurs courantes dans le choix de r\u00e9ponses. Comme pour la question pr\u00e9c\u00e9dente<\/a>, vous ne devriez pas avoir de probl\u00e8me \u00e0 r\u00e9soudre la question si vous disposez d\u2019une connaissance g\u00e9n\u00e9rale des instruments de comptage et des calculs qui y sont associ\u00e9s. Cependant, les choses peuvent se compliquer si on tient compte des incertitudes. Voil\u00e0 pourquoi il faut se pr\u00e9parer \u00e0 ces examens!<\/p>\n

Comme je l\u2019ai mentionn\u00e9 \u00e0 plusieurs reprises dans les chroniques pr\u00e9c\u00e9dentes \u00ab\u00a0Pr\u00e9paration \u00e0 la d\u00e9signation (A)ACRP\u00a0\u00bb<\/a>, lorsqu\u2019il est question d\u2019instrumentation et de comptage, ma r\u00e9f\u00e9rence pr\u00e9f\u00e9r\u00e9e est Radiation Detection and Measurement<\/em>[1<\/a>] de Knoll. On y trouve d\u2019ailleurs une section compl\u00e8te r\u00e9serv\u00e9e \u00e0 la propagation des erreurs dans les calculs. Ce livre fait partie de la liste des lectures recommand\u00e9es dans le document \u00ab\u00a0Processus d\u2019agr\u00e9ment professionnel de l\u2019ACRP<\/a>\u00a0\u00bb sur le site Web de l\u2019ACRP.<\/p>\n

De retour \u00e0 notre question, le taux de comptage est donn\u00e9 par\u00a0:<\/p>\n

\"\"<\/p>\n

La question nous indique que le taux de comptage est de 361 cpm (inutile de le calculer puisque c\u2019est la seule option offerte)! L\u2019\u00e9cart-type correspondant pour les comptes totaux est donn\u00e9 par :<\/p>\n

\"\"<\/p>\n

Donc, l\u2019\u00e9cart-type pour les comptes est donn\u00e9 par la racine carr\u00e9e de 1\u2009805.<\/p>\n

Maintenant, voici l\u2019information cl\u00e9. R\u00e8gle g\u00e9n\u00e9rale, on suppose que l\u2019incertitude sur le temps est tr\u00e8s faible; si faible que nous pouvons, par convention, la consid\u00e9rer comme \u00e9tant constante.<\/p>\n

Ainsi, m\u00eame sans tenir compte des conseils avis\u00e9s du sous-comit\u00e9 de l\u2019agr\u00e9ment et en utilisant la liste des lectures recommand\u00e9es, vous pouvez chercher dans les profondeurs de votre esprit (en revoyant vos premiers laboratoires) et vous rappeler la propagation d\u2019erreurs.<\/p>\n

La propagation d\u2019erreurs lors d\u2019une division par une constante (ici, le temps) implique la recherche de l\u2019erreur fractionnelle. Dans cet exemple, c\u2019est donn\u00e9 par\u00a0:<\/p>\n

\"\"<\/p>\n

Certaines personnes auraient pu \u00eatre tent\u00e9es de calculer le taux d\u2019abord, puis de chiffrer la racine carr\u00e9e de ce r\u00e9sultat (361 \u00b1 19 cpm). D\u2019autres auraient pu mentionner uniquement l\u2019incertitude sur les comptes (361 \u00b1 42 cpm). Dans l\u2019exemple donn\u00e9, vous auriez rapidement su que vous n\u2019\u00eates pas sur la bonne piste, puisque ces r\u00e9ponses ne sont pas dans les choix offerts. D\u2019autres questions pourraient ne pas \u00eatre aussi g\u00e9n\u00e9reuses et proposer des r\u00e9ponses qui incluraient des erreurs de calcul courantes. Soyez prudents ! V\u00e9rifiez vos op\u00e9rations !Donc, notre r\u00e9ponse finale avant d\u2019arrondir ressemble \u00e0 361 \u00b1 8,497 cpm. Par convention, l\u2019erreur d\u2019incertitude est toujours arrondie \u00e0 la hausse (l\u2019\u00e9cart-type est pareil, m\u00eame si on ne conserve qu\u2019un seul chiffre significatif). Dans tous les cas, la r\u00e9ponse la plus pr\u00e8s est c. 361 \u00b1 9 cpm.<\/p>\n

La question pour le prochain num\u00e9ro<\/strong> :<\/h1>\n

Vous avez une source scell\u00e9e de Ni-63 de 555 MBq en entreposage permanent. \u00c0 quelle fr\u00e9quence devez-vous proc\u00e9der \u00e0 un test de fuite?<\/p>\n

a. Une fois par mois
\nb. \u00c0 tous les 12 mois
\nc. \u00c0 tous les 24 mois
\nd. Uniquement lorsque la source est \u00e9limin\u00e9e<\/p>\n
