Match the appropriate type of radiation for each description/application:

For the following radioactive decay series, indicate what type of decay takes place at each step:R88226a →1 R86222n→2 P84218o →3 A85218t →4B83214i →5 T81210l →6P82210b →7 H80206g →8 T81206l →9 P82206b

For each of the following statements, evaluate whether the expressed inequality is true or false.  Choose those which are correct.

A nuclide with a half-life of 5 days will have what fraction remaining after 15 days?

You are an operator on facility with stored radioactive materials, and that portion of the facility has experienced a fire.  Since you know the region of the facility where the fire took place, you are being asked to help lead a team to identify, characterize and eventually secure any possible radioactive sources that might have been exposed in the incident.Choose the most appropriate piece of equipment for each task the team is likely to have to perform.  Some answers may be used more than once, some may not be used.

Fill in each blank with the most appropriate term.  Some answers may be used more than once, some may not be used.In (1) ______, changes occur within an atom’s nucleus rather than its electron cloud. Each nuclide is defined by its (2) ______ (number of (3) ______) and its (4) ______ (sum of (5)________). Writing a (6) ______ requires that both the total mass numbers and atomic numbers balance, reflecting the (7) ______ of mass and charge. Unstable nuclides may emit an (8) ______ particle — a high-energy helium nucleus — reducing mass by 4 and atomic number by 2; a (9) ______ particle — a high-energy electron, converting a neutron to a proton; or a (10) ______, shedding excess energy with no change in mass number or atomic number. The rate of decay follows an exponential law characterized by a nuclide’s (11) ______.

Gamma decay differs from alpha and beta decay because:

Balance the following nuclear equations by determining the values for the nuclide X: Equation Nuclide N 7 14   +   X b a   →   O 8 17   +   p 1 1 X b a where: X = [BLANK-1], a = [BLANK-2], b = [BLANK-3] U 92 235   +   n 0 1   →   X b a   +   Z 40 97 r   +   2 n 0 1  X b a  where: X = [BLANK-4], a = [BLANK-5], b = [BLANK-6] B 5 10   +   n 0 1   →   X b a   +   α 2 4  X b a  where: X = [BLANK-7], a = [BLANK-8], b = [BLANK-9]  C 27 60 o   →   X b a   +   β – 1 0   +   2 γ 0 0   X b a  where: X = [BLANK-10], a = [BLANK-11], b = [BLANK-12] C 96 246 m   +   X b a     →     N 102 254 o   +   4 n 0 1  X b a  where: X = [BLANK-13], a = [BLANK-14], b = [BLANK-15] H 1 2   +   X b a     →     H 2 4 e   +   n 0 1  X b a  where: X = [BLANK-16], a = [BLANK-17], b = [BLANK-18] M 12 25 g   +   α 2 4   →   H 1 1   +   X b a  X b a  where: X = [BLANK-19], a = [BLANK-20], b = [BLANK-21]
