The material that contained in the airtight box which killed the man should be identified. Concept introduction: Unstable nuclei emit radiation spontaneously to become stable nuclei by losing energy. This process of emission of radiation by unstable nuclei is known as radioactive decay. These emitted radiations may be alpha radiations( α ), beta radiations( β ) or gamma radiations( γ ) These unstable nuclei are the nuclei with more than 83 protons and which do not lie within the belt of stability. To identify: The material that contained in the airtight box which killed the man

A Water Quality Standard will be developed for radioactive isotope “Iron-55” which has physical (radioactive) and biological half-lives of 2.7 and 1.6 years, respectively. Through toxicological studies scientists decided “spleen” as the critical organ and the critical accumulation of Iron-55 in spleen has been determined to be 0.5 gram. Assuming radioactive exposure is only due to drinking water consumption and average life expectancy is 75 years. a) What should be the Maximum Concentration Level (MCL) as mg/L for Iron-55 in drinking water. b) How long does it take to eliminate 95% of this radioactive isotope from human spleen after the person gives up on drinking water contaminated with Iron-55?

Iridium-192 is one radioisotope used in brachytherapy, in which a radioactive source is placed inside a patient's body to treat cancer. Brachytherapy allows the use of a higher than normal dose to be placed near the tumor while lowering the risk of damage to healthy tissue. Iridium-192 is often used in the head or breast. Use the radioactive decay curve of iridium-192 to answer the three questions. 100- 90 - 80 – 70 - 60 - 50 - 40 - 30 - 20 - 10 - 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 Time (days) If the initial sample is 4.50 g, what mass of the original iridium-192 remains after 35 days? Sample remaining (%)
