'λ' is called the disintegration constant or decay constant. Since rate of disintegration or change is proportional to the number of atoms present at that time, the relation becomes. The negative sign indicates the number of atoms decreases as time increases. At this instant of very small number of atoms dN disintegrate in a small time dt the rate of change of A into B is given -dN/dt. Suppose the number of atoms of a radioactive substance present at the start of observation, i.e., when t = 0, is No and after time t the number of atoms remaining unchanged is N. Radioactive disintegration is similar to such a chemical reaction as one radioactive species changes into other. Where n is a whole number.ĭisintegration constant: A chemical reaction whose rate varies directly to the concentration of one molecular species only, is termed as first order reaction. Thus, for the total disintegration of a radioactive substance an infinite time will be required.Īmount of radioactive substance left after n half life periods N = (1/2) n N 0 and total time T = n × t1/2. After two half life periods (2t1/2) it becomes = No/4 and after n half life periods (nt1/2) it becomes = (1/2) n N 0. After one half life period (t1/2) it becomes = No/2. Let the initial amount of a radioactive substance be No. Half life periods vary from billions of years for some radio isotopes to a fraction of a second. It is defined as “time during which half the amount of a given sample of the radioactive substance disintegrates”. Rutherford introduced a constant known as half - life period. The law of radioactive disintegration may be defined as the quantity of radioactive substance which disappears in unit time is directly proportional to the amount of radioactive substances present or yet not decayed. The rate of disintegration of a given substance depends upon the nature of disintegrating substance and its total amount. The radioactive decay of the different radioactive substances differ widely. Maybe even have them be a quest hub for "Item of the Week" type hunts.The rate of disintegration of a given substance depends upon the nature of disintegrating substance and its total amount. Just give them a good name and have a fun voice, cause I have a feeling you'll be using them a lot once the PCs pick up on what can be done. And you should include lots of monster parts in your list cause they could use the help in selling items if you have an NPC that helps deal in those kind of reagents.
but you'll need to develop your own ingredient price list to help offset it. I could certainly price out different ingredients as bringing the price down though. Even at half cost you should be looking at 25,000 gold or more. but there is going to be a significant gold expenditure even with the ingredients.
I'm liking all the talk of components from everyone though. I really don't think this upper level of wand would fit in to the Very Rare category. Just to buy a wand in this kind of category would cost you 5,001 - 50,000 GP for a Very Rare item or much more than that for a Legendary. everything is much more expensive at this end of the scale. Not only are there simply NO items that have 50 charges. He also should probably roll percentage die and take half the number rolled (so if he rolls 53, he gets 26 charges).
WAND OF DISINTEGRATION PLUS
11 x 6 x 750 for 50 charges, plus he needs to incorporate the hair from a Lich into the wand shaft to create this wand.
