“Strontium-90 is a pure beta source.” How could a physicist test this statement?
A 70-kg worker is accidentally exposed for 2.0 minutes to a 21-mCi source of beta radiation from a sample of strontium-90. (a) What is the activity of the radiation source in cps?(b) Suppose that each beta particle has an energy of 0.547 MeV (1 MeV = 1.609 x 10-13 J) and 45% of the radiation is absorbed. Assuming that the absorbed radiation is spread over the person’s entire body,calculate the absorbed dose in rads and in grays.
(c) If the beta particles has an RBE of 1.0, what is the effective absorbed dose in mrem and in sieverts?
Explain why 231-Th-90 is likely to be a beta minus emitter

- Tritium (t1/2 = 12.33 y) is mostly produced for military purposes. The United States stopped producing tritium in 1988 but resumed in 2003. In 1996 it was reported that the United States had only 75 kg of tritium stockpiled. If none of it was used by 2003, how much tritium remained?arrow_forwardIridium-192, a beta emitter, is used in medicine to treat certain cancers. The 192Ir is used as a wire and inserted near the tumor for a given amount of time and then removed. The 192Ir wire is coated with pure platinum, and is sold by diameter and amount of radiation emitted. One type of wire sold is 221 mm long, has a linear apparent activity of 30–130 MBq/cm, an active diameter (which is the iridium-192) of 0.1 mm, and an outer diameter (the platinum) of 0.3 mm.

- CSDA range Determine the expected range of 2 MeV beta radiation in polyethylene, Aluminium and air. Use the ESTAR database on the NIST website to find the CSDA ranges (to 4 significant figures): R(px) for polyethylene = 9.375E-01 ✓g/cm² R(px) for Al= 1.224E+00 ✓ g/cm² R(px) for air- 1.094E+00 x g/cm² Looking at the 3 values you have found, the statement in the lab notes that the range is 'inversely proportional to the density p of the material and not dependent on its structure or any other properties' is a useful rough approximation because the px values are similar even if not exactly the same The values given are density times thickness (px). To find the actual range (x) we just divide by the density.arrow_forwardA radioactive source, which emits beta-particles, is used as shown in Fig. 12.1 to detect whether cartons on a conveyor belt have the required volume of pineapple juice in them.

Radioactive dating with 14C revealed that this person was alive approximately 5 300 years ago. Why did scientists date a sample of Ötzi using 14C rather than 11C, which is a beta emitter having a half-life of 20.4 min?arrow_forward(DIFF:D)A living specimen in equilibrium with the atmosphere contains one atom of 14C (half-life = 5 730 yr) for every 7.7 x 1011stable carbon atoms. An archeological sample of wood (cellulose, C12H22011) contains 16mg of carbon. When the sample is placed at the centre of small, spherical shield (radius =4cm), and a beta counter of the area of 5cm2 (and 100 % efficiency) is set at the surface of the shield facing the sample through the aperture of the same size, 906 counts are accumulated in one week.
