In a science fiction movie, a strange object is discovered buried deep in the ice of western Antarctica. It appears to be a radioisotope thermoelectric device from a spacecraft, the function of which is to convert thermal energy released in the decay of its radioactive contents into electrical energy. The radioactive material is identified as americium-241 (²⁴¹₉₅ Am), which has a half-life of 432 years.

(a) If ²⁴¹₉₅ Am undergoes alpha decay, what is its daughter nucleus?

(b) What is the activity you would expect for 1.00 g of ²⁴¹₉₅ Am (in Bq)?

(c) In the movie, 1.00 g of material is extracted from the device, and the activity is measured to be 4.00 × 10¹⁰ Bq. Assuming the device was initially loaded with 100% ²⁴¹₉₅ Am, how old is the device? Express your answer in years.
