1. The Russian ex-FSB officer Alexander Litvinenko was poisoned in 2006 with 10 µg of polonium-210, an α emitter that kills through radiation poisoning as molecules important to metabolism are ionized by the passage of the α particles. He died 3 weeks later.

(a) (5 pts) What is the nuclear decay process and what is the Q of the reaction in MeV? Show the full calculation.

(b) (5 pts) Find the kinetic energies (in MeV) of the α particle and the accompanying nucleus.

2. Refer to the previous problem.

(a) (3 pts) What was the initial activity of this dose of Po-210 in decays/sec?

(b) (3 pts) What fraction of the Po-210 sample decayed in the first 3 weeks?

(c) (2 pts) How many α particles were emitted in the first 3 weeks?

(d) (2 pts) If the average ionization energy of molecules in body cells is 2 eV, approximately how many molecules were ionized in the first 3 weeks?

This problem is for Cost Accounting Exercise 10-3 (chapter 10 Ex. 3) The chief executive officer of Acadia, Inc. attended a conference in which one of the sessions was devoted to variable costing. The CEO was impressed by the presentation and was asked that the following data of Acadia, Inc. be used to prepare comparative statements using variable costing and the company's absorption costing. The data follow: Direct Materials....................................................................... $90,000 Direct Labor............................................................................. 120,000 Variable Factory Overhead........................................................ 60,000 Fixed Factory Overhead................................................................

Time(weeks): 0 | 2 | 6 | 10 Level: 210| 200 | 190| 180 1. The table above gives the level of a person’s cholesterol at different times during a 10-week treatment period. What is the average level over this 10-week period obtained by using a trapezoidal approximation with the sub-intervals [0, 2], [2, 6], and [6, 10]? 2. Water is pumped out of a lake at the rate R(t)= 12 square root (t/(t+1) cubic meters per minute, where t...

Business 210 ch 10 11 12 15 T F 1. A p-value of .008 in hypothesis testing means there is only a .8% chance we could get such sample statistics from the population if the null hypothesis is as stated. Such an event is considered unlikely and we would reject the null hypothesis. T F 2. As a general rule in hypothesis testing, it is always safer to set up your alternate hypothesis with a greater-than or less-than orientation. _____3....
